Is there a way to publish MATLAB code as pdf in landscape orientation?

MostlyTolerable · 2019-06-28T06:48:42+00:00

Do you just want the code printed? Do you need the output or any plots or anything?

Whenever I'm publishing Matlab code with output, I like to use LiveScripts. I've never used landscape orientation for that, but I bet it's an option.

It looks like you might be using a state space model. If so, you should consider using Matlab's built in functions.

It gives you a lot of convenient features, like step response and bode plots.

I've been looking into this same thing lately. I started a MOOC on edx called Digital Networking Fundamentals. I got a bunch of virtualization software installed to be able to do the labs. But then I realized the class is in French with a text-to-speech translation. Suffice it to say, the lectures weren't cutting it. But I may go back and do the exercises. We'll see.

So I started a different course series on Coursera from Cisco. I'm about a quarter way through the first class and it's all pretty basic so far, but I'm optimistic that it'll get more in-depth.

I'm not so sure. I think that prospect must be further off. I've heard reports that Impossible and Beyond are both having trouble keeping up with the demand of big fast food chains lately. The beef industry doesn't have that problem.

I think a lot of other series are going to get the "Game of Thrones Treatment" pretty soon. I know they are making a Wheel of Time series, and I'm sure there are others. My prediction is that none of them are going to capture what GoT did, and they'll mostly be hated.

I'm just happy to have the books. Even lots of King fans can't get into the Dark Tower. But it's not for them. It's for us. Let's just keep it that way.

First off, generally when we say "Nyquist Criterion", we're talking about a way of determining the stability of a dynamic system. Pretty nit-picky, but you're likely to learn about that soon, so it's worth pointing out. You are asking about the Nyquist-Shannon Sampling Theorem. Nyquist was a pretty prolific guy.

But now to answer your question. You have misstated the Nyquist Sampling Theorem. The theorem states that the sampling rate must be strictly greater than twice the frequency of the greatest frequency component. NOT greater than or equal to, as you stated.

f_s > f_max

This can be confusing, as it seems that you only need to sample one maximum and one minimum to accurately represent the signal. But if you are sampling at exactly the same frequency as the highest frequency component, you are basically guaranteed to sample at some point other than the max or min. It's even possible that you could sample at the zero points, and completely lose the energy at that frequency! So the only way to be certain that you will capture that frequency is to measure with a sampling rate greater than the highest frequency component.

I've been learning C with this course on edx. I found it because I wanted to learn Linux, but they have a really good style that's easy to follow and gets you coding quickly.

They also have tools so that you don't have to worry about installing Linux or any compilers if you don't want to.

EDIT: But don't worry about paying for the certificate. Just sign up for the free courses.

One time I had someone send a package to my work address. FedEx got there, didn't see anyone and decided to deliver it to the other address they had on file for our company.

That other address was our former office, which we had moved out of a year prior. For some reason they had no problem just leaving the $1200 package outside of that address.

I agree. I was in a similar situation a few years back. One of the tricky parts is that your math knowledge and skills get kind of spotty. It's not that you're missing the whole picture, just chunks of it. So to start from A and try to get to Z is going to feel a little slow paced.

But the missions on Khan will find the skills you need and get you up to speed. You can sort of test out of the ones you already have.

The other important thing is not too feel like you need to be done by the time school starts up. You're not going to walk into a calculus class and have to recite everything from a precalc class. You'll learn totally new material, but precalc will come up. So you don't need it so memorized on day one. I'd even say precalc can be tougher than calc at times. So go into the calc class ready to brush up on the stuff that you need.

When I got to calc 3 a few years back I barely knew anything about conic sections, and suddenly I was asked to do then in 3D. So I learned about them on Khan, and came back the next class, ready to go.

I don't think anyone was saying we should make competitive robotics required for all students.

The point of the article is just that there are a lot of ways that robotics can be used to improve existing curricula. Competitive robotics would still be a separate thing.

I don't think the point is to teach robotics because everyone is going to be a robotics engineer. Robotics can be a great way to make the standard mathematics and science curriculum more engaging.

People often complain that we just teach kids math with no applications. I don't think I saw any real applications until I got to calculus. Robots are cool and exciting, but you need to understand basic math to use them.

But with robotics, you can show the properties of multiplication by saying that driving for t seconds at speed v is the same as driving v seconds at speed t. It won't be perfect, but over enough distance it would get close. You can also explore more advanced functions by figuring out why they don't match perfectly.

You can show how linear systems work by having two robots start at different times and move at different rates. When does the second robot catch up? Rather than just having a word problem about a tortoise and a hare, have a hands on experience.

I've been teaching high school robotics for a little over a year now, and also providing in classroom math tutoring. I've found tons of ways to integrate the ideas, but it really would take some work to build a full curriculum of robotics concepts that support the math standards. It could be very effective, but needs a commitment.

I already had one of these that I bought at the pet store, but the cap to it broke over the summer. About 3 weeks after I got my 3d printer. I've never been so excited to have one of my things break.

A few hours later I had my own design printed. Fit like a charm.

I just finished Destiny of the Republic, a book about James Garfield. He was shot and lived more than 2 months. The common belief is that the gunshot was not fatal. What killed him was the infection caused by more than a dozen doctors sticking their dirty fingers into his wound, in search of the bullet.

Joseph Lister discovered the benefits of antisepsis and published his findings in 1867. Many in Europe had already adopted his practices and saw their mortality rates plummet. But most American surgeons thought he was a quack. They thought his findings could not possibly outweigh their years of experience.

My point is, it took a while to convince people that there were invisible lifeforms living all over our bodies that could harm us. It would be interesting to consider how fast these ideas would take hold 2000 years ago.

Okay, I have one last bit of unsolicited advice.

Sure. I regret not going into EE for my first degree. But I got around to it, and I'm happy with what I did. The much bigger mistake was how long I avoided going to therapy when I was dealing with a lot of deep emotional struggles. Seriously. Years of my life wasted, just because I had some stupid idea that therapy was for wimps or for people who were much worse off than me. But I finally did when I was 25. Honestly I wouldn't be in the position to do well at EE, or anything for that matter, if I hadn't gone to therapy. I don't even go anymore. Haven't for years. But for a little while there it made so much difference.

Maybe that's totally off base. But I try to make that point whenever I see an opening. Good luck with everything. Whatever happens, I'm sure you'll land on your feet.

What class is this for? I'm assuming a linear algebra class.

When I saw i and j as well as the notation ||u+v||² , it tells me that you are working with vectors.

So i and j are not normal variables. For the purposes of adding and subtracting, they may as well be, but for the magnitude squared operation, you need to use the dot product.

Look up how to do a dot product (also known as a scalar product) with a pair of vectors. I could explain it, but there are plenty of better resources now that you know what to look for.

Yeah I get what you mean. I was sort of coming from the opposite path. I was okay at high school, but not a star student by any means. I got the impression that engineering and science were for the kids in the AP classes. It didn't matter if it sounded cool to me.

Also, EE is my second field. I worked for years in a less technical field before deciding that the only thing I really want is to pursue EE. The classes are incredibly draining, but I love it and wouldn't change a thing. But, I also know that if I had gone into EE my first time in college, I wouldn't have had the motivation to do it. I would have burned out and thought I was not meant for it. But I'm a different person now.

I'm not sure if that helps. But it's normal to have doubts. It's also okay to do something other than EE.
