Tutorials required for MATLAB programming

I want to create a simple program to ease repeated calculations that I have to do with different values. I want the program to be such that I enter two values each time and get the result after calculations, based on the values I have entered.
It is very simple to do in C language, but I have to do it in MATLAB and I don't have any experience with it.
So, please anyone provide me with some related tutorials for it.
