MATLAB coding question: This function outputs a matrix using Gaussian elimination.

Fix this function to not give NaN values when a = [0,2,2,0;0,2,3,4]. Please give the corrected function code that works in such situations with no NaN values as output.

function a = gauss(a) [m,n]=size(a); for j=1:m-1 for z=2:m if a(j,j)==0 t=a(j,:);a(j,:)=a(z,:); a(z,:)=t; end end for i=j+1:m a(i,:)=a(i,:)-a(j,:)*(a(i,j)/a(j,j)); end end end
