Trying to multiply a matrix by itself through writing a MatLab script which multiplies a square matrix (of size n × n) by itself. Write a MatLab or Octave script which implements Naive Gaussian elimination. The script should take a matrix, A and a vector b as inputs and returns the vector x as an output. Can't figure out these questions, any help is great thanks

If you don't know how to multiply a matrix by itself in MATLAB, you have absolutely no hope of writing a Gaussian elimination routine. You should start reading the beginning tutorials in the MATLAB help documentation.
