Know how to write the Forward Sweep part of Gaussian Elimination from scratch. For example:

function [Aupper] = myForwardSweep(A, b)

[nRows, nCols] = size(A);

if nRows ~= nCols

error('Must be a square coefficient matrix');

else

n = nRows;

end

m = 0;

Aupper = [A b];

for i = % Question 18

% Do a linear transformation to each row:

for j = % WHAT GOES HERE

m(i, j) = % WHAT GOES HERE

for k = % WHAT GOES HERE

% WHAT GOES HERE

end

end

end

Your completions should use the variables in my existing code.

please answer in matlab code
