Using MATLAB, develop an M-file to determine LU factorization of
a square matrix with partial pivoting. That is, develop a function
called mylu that is passed the square matrix [A] and returns the
triangular matrices [L] and [U] and the permutation P. You are not
to use MATLAB built-in function lu in your codes. Test your
function by using it to solve a system of equations listed below in
part 3. Confirm that your function is working properly by verifying...
