MATLAB has two built-in functions for finding the inverse of a matrix:inv()andbackslash. MATLAB inv() Function In MATLAB, to find matrix inverse generally inv(A) function is used. Now we will cover the details of this function and how we can use it in MATLAB code. Syntax The syntax f...

I found the problem now. The code that I pasted below did not work as I forgot to change the 'int' in sizeof to 'size_t'. Thank you guys for pointing out the errors!!! ;) You saved my day!the
