>>60281627
No. I have to learn this shit on my college...

>>60281647
It was your choice to go to that college.

>>60281587
MATLAB is mostly idiot proof.

if you dont use it on other classes, you probably are on shit tier college.

I use it on math, mechanical engineering, electrotechnic, computer science, automatics and others

>>60281706
Yeah... It's for Introduction to Computer Science. Soon, I'll learn R, too. For statistics.
But, I like C, and a little bit of Python.

I DON'T WANNA LEARN THIS SHIT!

>>60281701
Except when you somehow manage to fill your whole RAM using a loop, causing the PC to become unusable. Whoops.

because everyone else uses it

>>60281587
atleast it's not python

>>60281587
Suck It up faggot. It's a very powerful tool that I used for more than half of my damn degree. Every course involving signal or image processing gave us HW using Matlab, plus it can be useful to solving some nasty equations iterativly. Their wiki/help Center is very helpful.
Somewhat big community.

>>60282209

This shit is expensive...
Can I use FREEMAT for everything?

>>60281863
Why not use what the teacher uses? Makes no sense really

>>60282284
Yeah, I'm using octave
But I would like to use matlab instead

I'm done... The manual book have 2,500 pages!

>>60282232
Hell no. Our faculty computer all have them but I usually just pirated it. Recently my institute got a license agreement with Mathworks so every student now has access to an official license (too bad they remembered about it in my last semester).

>>60282553
Matlab is useful for what kind of shit?

I don't know. Use Python if you don't feel like it.

Also, AVOID For-loops. VECTORIZE, ALWAYS. I've also found that figures and plots work best when saved as .pdf if you want to import into LaTeX, but I'm sure there is an even better way.

I've used it through all of my bachelors and most of my masters degree, in engineering physics and machine learning respectively.

Also generally, it's easy to prototype and test code before implementing it for real.

Matlab is the most disgusting shit ever.
I don't even like Python, but Scipy, Mathpy, and pandas are vastly superior.
Or just use FORTRAN.

I almost threw up when I started learning matlab and found that out. I just wanna use python, why must my profs shove this proprietary shit down my throat?

GPL is fucking communism. MIT/BSD is freedom like do whatever you fucking want.

>>60281587
It's good because it has a lot of functions for calculus and high end math things which will make your life easier if you need to use them. If you don't have to use a lot of math then you shouldn't use it.

The best thing about MATLAB is also the worst thing about MATLAB.

It's "super powerful" and easy for prototyping, which means that a lot of people that are actually unable to program have probably contributed to the codebase that you have to use.

Some of the worst code I've seen in my life was MATLAB Code. It's even worse than python in that regard.

>>60284213

Opensource is not communism, Jesus a capitalist society necessitates free flow of ideas and information. Being able to do this outside of other peoples interests aids this. You can fuck off with your sunk cost bullshit ideology. Take a swan dive off a bridge you recursive double faggot.

>>60285333
Yes I am mad, GPL is not communism.

>>60285261
As far as I know matlab is not even a full CAS

>>60285316
> Opensource is not communism
Correct. On the other hand GPL has communist elements in it, because it creates non-profit circuit inside the capitalist society which allows people to step out market relations at least in some part of their life.
> a capitalist society necessitates free flow of ideas and information
Wrong. Capitalist mode of production enforces property relations wherever it can, see https://en.wikipedia.org/wiki/The_Great_Transformation_(book), even in the areas where there are literally no scarcity, like the fucking IP, or patents, or scientific publishing.

>>60285558
>creates non-profit circuit inside the capitalist society
Nope, everybody can profit from GPL, and I mean everybody. Even is a non-profit made something with the code someone else can take that code, improve it and make money.

This is not just free as in freedom, this is "free as in free market".

>>60285592
Communism is about Commons. GPL takes any piece of code and puts into commons from which it can never be transferred back to the market: https://youtu.be/em0FY9JDrJI?t=2h8m31s This forever removes the market element -- articial scarcity and exclusion -- from it and leaves someone only ability to sell some services, like support and maintenance, but not the access.

>>60285207
You tell them comrade. Americans are like Nazis, afraid of a few dozen million dying at gulags here and there. Such capitalist scum. And always afraid of the starving as well. Much trash.

I can't believe so many autists fall for this bullshit. Code doesn't magically disappear off the face of the internet just because someone later copied it and put it in a close source program. The original code is still out there for anyone else to use. What GPL does is RESTRICT ~MY~ FREEDOM to do whatever I want with MY OWN CODE that is added in addition to the "free" code. If you want to work for free, that is fine. BUT it is Communism to demand everyone else does things the same exact way (equality of results).

>This forever removes the market element

There's nothing stopping people from selling GPL code. Idiots will buy anything.

GPL prevents you to close the source of your program, or letting others do the same; which is against freedom.

FUCK OFF, M**t SHILL

>>60285974
Because you are speaking in the abstract which is of no interest. For the concrete subjects of capitalist social relationships the wikipedia pages (which you can sell), or gpl code (which you can sell) or air (which you can sell) are not acquired via market exchange, which means they are not, effectively, a commodities, but just use-values

Section 6 is ugly and you used a for loop for what should be a one liner.

m_zerowew = m_zerowe(find(m_zerowe>=a && m_zerowe<=b));

You may also be able to save some computation time by using poly2sym() then subs() rather than all those for loops to roll up your polynomials from coefficients.

Inbuilt methods are generally better for MATLAB and documentation is your friend. Can't really give advice on the math side since your variables are in polish and I'm lazy.

The 1 index takes getting used to. Iirc it was carried from when MATLAB was written in FORTRAN and has been carried along. While it's annoying for CS-types, math people are used to it.

Because you are probably learning engineering or scientific computing, albeit Python and R are pretty much better at it if you can't afford learning C or Haskell properly. MATLAB/Octave/Scilab is standard for engineering stuff, however Python and R cover a wider scope of problems by their huge availability of libraries.
