M=1;Kp=100;
P2=M+(1/Kp);P3=P2+1i*w;
U7=exp(y*sqrt(P3)).*(1-erf(y/(2*sqrt(t))+ sqrt(P3*t)));
Error using erf (error function)
Input must be real and full.
Error in
U7=exp(y*sqrt(P3)).*(1-erf(y/(2*sqrt(t))+ sqrt(P3*t)));

There is a way you can get around the restriction. If you use the symbolic toolbox, then the erf() function for it accepts complex inputs. To use the symbolic toolbox, at least part of the expression needs to be symbolic. For example if instead of sqrt(P3*t) you used sym(sqrt(P3*t)) then that would be enough. The result of the erf would be symbolic, so you would probably want to double() it.
