Subsection 5.3.3 LU factorization with partial pivoting Having introduced our notation for permutation matrices, we can now define the LU factorization with partial pivoting: Given an \(m \times n \) matrix \(A \text{,}\) we wish to compute

Employ the result of (a) to compute the determinant. (c). Repeat (a) and (b) using MATLAB. in matlab.

I am having problems with the first part of my code where i decompose the matrix in to an upper and lower matrix. Partial pivoting (P matrix) was added to the LU decomposition function. In addition, the LU function accepts an additional argument which allows the user more control on row exchange. Matlab lu() function does row exchange once it encounters a pivot larger than the current pivot. This is a good thing to always try to do. MATLAB LU Decomposition Partial pivoting.
