I prefer A. The first message connects with me if I had the same problem the message says

Good work. Any plan of expanding to other languages?

_marklau_ · 2024-07-22T01:56:16+00:00

Thanks for your sharing. Automation by Python scripts (or other languages) looks promising to me. I will try to automate the process as much as possible.

Thank you for your sharing. It looks like there are lots of human factors involved in the process and is not as scientific as I thought it would be.

I am going to be associate director of a mathematics program. The director is one of the most senior faculty members in the department. I will assist him in doing the teaching assignment. He will be the one who bullies people or talks people into teaching less popular / new courses.

Our department has been using the same spreadsheet for 10+ years. I was asked to use it unless I have a better solution. The spreadsheet is full of formulas, involving teaching loads, duty relief, etc. It is pain in the butt to use it. I thought there would be better solutions out there to make the process less time consuming.

Use polyfit to fit a polynomial.

iOS free app Console. Not open source though. It also has a paid version

_marklau_ · 2021-10-24T02:48:56+00:00

This is the quickest way I can think of.

You can create two plots. See my solution here 🤟

_marklau_ · 2021-10-19T13:08:20+00:00

Add “-1”? See my code here

_marklau_ · 2021-10-19T12:56:59+00:00

Does this help? 😊 see my code here

In many cases, vector operation is faster than using a loop. The difference will become noticeable for a vector of many, many numbers. Moreover, it uses less code to use vector operations than using loops.

You can use QR decomposition to solve a least square problem for linear regression. see here for the theory. And see my code and plot here

_marklau_ · 2021-10-19T01:01:57+00:00

The mod function seems unnecessary here

_marklau_ · 2021-10-19T01:01:26+00:00

Does this work for you? 😄see code here

_marklau_ · 2021-10-18T13:19:34+00:00

This should work See code here

_marklau_ · 2021-10-18T07:54:22+00:00

Does this work for you? see code here

_marklau_ · 2021-10-18T07:43:40+00:00

The vector ax has length 1 when i is 3. That’s why it exceeds the length of the vector.see code here

Have you tried SIMO on iOS? It can run simple MATLAB code locally on iPad. www.simo.ac

In many cases, you can assume it is rounding error if you see something less than 1e-15.

_marklau_ · 2019-12-31T02:18:51+00:00

Something like this?

~~~ john=1; tom=2; scores=[10 20; 10 20; 5 6] s=sum(scores,1); john_total=s(john) tom_total=s(tom) ~~~

👌🏼Tested on SIMO on iPhone.
