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...

In this exercise you will work with LU factorization of an matrix A. Theory: Any matrix A can be reduced to an echelon form by using only row replacement and row interchanging operations. Row interchanging is almost always necessary for a computer realization because it reduces the round off errors in calculations - this strategy in computer calculation is called partial pivoting, which refers to selecting for a pivot the largest by absolute value entry in a column. The MATLAB...
