I am doing some research and I want to use software like Scilab or MATLAB to plug in values for a, for example, $2\times 2$ matrix and see how the linear combination of vectors' direction and magnitude are changed when different numbers (or eigenvalues, etc). are manipulated. However I tried scilab and it is extremely hard and I don't know how to write matrices in scilab. In fact, what is the best software to do this in?
I can quickly clarify any unclearances.
I FORGOT TO ADD I HAVE A MACBOOK.
