I have below code for a contour plot bu I faced with "Matrix dimensions must agree.".
How can I fix it?

conj(phiy) zeros(size(phiy))];
jy12=((v1'.*H2y.*v2).*conj(v1'.*H2y.*v2));
deltaE12=E2-E1;
fermi1=1/(1+exp((E1-u)/T));
fermi2=1/(1+exp((E2-u)/T));
sigma_xx=(iform.*omega.^-1).*(jy12).*(fermi2-fermi1).*( (omega+deltaE12+iform.*delta2).^-1-(omega-deltaE12+iform.*delta2).^-1 );
contour(e,EE,sigma_xx,500)
