I am trying to find the rref form of a matrix with imaginary components. Not sure if my lack of linear algebra is what's holding me back or my matlab knowledge. Below is my code.
clc
clear
node1 = [complex(.25,-.2) complex(0,.2) complex(12.46,-.9)]
node2 = [complex(0,.2) complex(.1,-.2) 0]
a = [node1; node2];
rref a
I'm getting these errors
Error using norm
First argument must be single or double.
Error in rat (line 57)
tol = 1.e-6*norm(X(isfinite(X)),1);
Error in rref (line 26)
[num, den] = rat(A);
Error in ecehomework7 (line 6)
rref a
yes this is for a homework assignment but I was specifically told I could use matlab in case that helps ease your consciousness, thanks in advance!

Ran in:
node1 = [complex(.25,-.2) complex(0,.2) complex(12.46,-.9)];
node2 = [complex(0,.2) complex(.1,-.2) 0];
a = [node1; node2];
rref(a)
ans =
1.0000 + 0.0000i 0.0000 + 0.0000i 37.5366 + 1.8226i 0.0000 + 0.0000i 1.0000 + 0.0000i 30.7584 -13.5565i
