probably you haven't define G before you used it.

have you assigned G= something inside bairstow.m??

i think no

Yup ... that's the problem. Put G = 0 at the end of bairstow.m

experimentX Group TitleBest ResponseYou've already chosen the best response.2
or out G = ... the value where you are outputting ... I can't even read your code. you sure know how to do complex thing.

and in end of the function according to what u said turn [X1(1:end) X2(1:end) x3] to G=[X1(1:end) X2(1:end) x3] and [X1(1:end) X2(1:end) y3] to G=[X1(1:end) X2(1:end) y3]
