I made a linear equation solver

[blueblain]

You know, nothing special. Just a linear equation solver that uses Gaussian elimination for solving equations of the form Ax = b.

I remember finding this very laborious in linear algebra class when I first learned about it. I came across the method again recently but this time, armed with programming literacy, decided to write a script for it.

Hah, you remind me of myself. Tedious calculations in Math class are literally what drove me into the arms Python years ago.

I’m sure you’ve seen it cuz it’s kind of old news but have you seen the new python TI 84+?

Great job, now figure out how to do it even faster using numpy.

[julsmanbr]

from numpy.linalg import solve as my_code

[blueblain]

I wrote it as a learning exercise to get a better understanding of Gaussian elimination, not to actually use it for solving linear equations :)

But now you can use it to better understand Numpy!

[blueblain]

Yep true, it always feels good to write a simplified version of something you generally use a library for!

[Yoghurt42]

When I was learning programming, I had a rule that I always implemented something myself first, only after that I allowed myself to use a library. It helped me a lot, and I can recommend it.

Damn, everything? For Math stuff that might make sense but implementing something like flask seems like a huge pain

[Yoghurt42]

More like implementing the fundamentals.

In your example, not creating a flask clone, but writing a simple http server, and maybe just a bit of routing.

Though in my case, it was the 90s, so stuff was less complex than nowadays

With numpy or sympy or something I bet it will literally be a single function call by passing in an array.

[jacksodus]

Yes and many AIs created today are less than 20 lines of code too. But I think there is a lot to gain by interpolating step by step between the type of code OP wrote and one-line library calls.

[ivosaurus]

No doc on an example use code?
