We cannot give you a copy of MATLAB. Answers is not customer support anyway. And even they don't just give out copies for anyone who asks for a free copy.
However, you can talk to your university. Do they have a site license for students? Many schools do. So you should start there.
If that is not an option, and you cannot pay for it, then you can consider using other tools. Octave, for example, is pretty close to MATLAB. Or Python - not so close, but not too hard to deal with.
