how to get a contour plot for a matrix with imaginary values

an error pops up saying the values must be real

p1source=(A1*exp(-j*k0*r1source))./r1source; %pressure from source 1

p2source=(A1*exp(-j*k0*r2source))./r2source; %preassure from source 2

p3source=(A1*exp(-j*k0*r3source))./r3source; %pressure from source 3

Pm1=p1source+p2source+p3source; %total pressure from all three sources

figure(1)

contourf(1:1:10,1:1:6,(pm1));

You can plot either ral, imaginary or absolute of the value.

contourf(1:1:10,1:1:6,real(pm1));   % to plot real part
contourf(1:1:10,1:1:6,imag(pm1));   % to plot imaginary part
contourf(1:1:10,1:1:6,abs(pm1));   % to plot absolute
