How to Download and Install Mathlab or Matlab (or Similar) for Free?

[nobahar]

Hello!
I have heard on occasions about Mathlab, or perhaps, Matlab, which can solve such things as matrices, etc.. Does anyone know where I can acquire this programme or one that is similar? Preferably a free one, but all recommendations are welcome.
Many Thanks,
Nobahar.

Thanks for the quick response. Is it user-friendly? For example, is the matrix presented in matrix form in which I can enter the components, or is it simiar to wolfram-alpha, which is always a chore to use?

It's pretty easy to enter matrices. If you want to change the (i,j) entry of a matrix M, you just type M(i,j)=x. You can also set whole rows or columns based on vectors you've constructed already. The output is a bit of a pain to read when it's bigger than the screen but it's manageable
