Hi all,
I am trying to plot a surface however, I get an error "X, Y, Z, and C cannot be complex." which means, apparently there are some xomplex values. However, I put the command to get only the real values and I get a blank graph with no points at all (it is obvious that there are solutions with real values). Couod you help me with that? here is the code
a=0.1735;b=0.19;c=0.3283;d=-0.017;[I,I_opt] = meshgrid(0.1:0.1:4.67,0.1:0.1:4.67);Z=exp(0.3524*(I-I_opt))*a*exp(b*I)*(1-a*exp(b*I))/(c*I_opt^d*(1-c*I_opt^d));redChannel=Z<1;colors = double(redChannel);surf(I,I_opt,real(Z),colors)zlim([0 10])
