The surface Z must contain more than one row or column.

Hi, I am pretty new to matlab and am trying to graph series using complex variables. I don't understand why I keep getting this error on line 16. Here is the code:

figure;

figure;
p=2; %range and domain of the graph
a=-p:0.1:p;
b=-p:0.1:p;
[A,B]=meshgrid(a,b);
x=(A+1i*B); %splitting the input into real and imaginary parts

C=real(summation(x));%the real part of the output
D=imag(summation(x));%the imaginary part of the output
t=surfc(A,B,C,D);%graphs the funtion. D is the colour gradient showing the imaginary output




function y = summation(x);
    y =complex(zeros(41))
    n=2;
    for k=1:n;
        f= x.^k;
    end
    y=sum(f)
end

Thanks in advance!

Is this? Please make C and D vectors with same girds points

p=2; %range and domain of the graph
a=-p:0.1:p;
b=-p:0.1:p;
[A,B]=meshgrid(a,b);
x=(A+1i*B); %splitting the input into real and imaginary parts
C=real(summation(x));%the real part of the output
D=imag(summation(x));%the imaginary part of the output
[C,D]=meshgrid(C,D);
t=surfc(A,B,C,D);%graphs the funtion. D is the colour gradient showing the imaginary output

I didnot check the role of function file.

Hope it Helps!
