The error indicates that the dimensions of the matrices are not consistent with respect to matrix multiplication. For more information regarding the “dimension of matrix,” refer to the MATLAB documentation:
Assuming that “X” and “Y” are matrices of size “m x n”, then the size of the matrix “x” must be “n x m” in order to satisfy compatibility.
X = zeros([m,n]);
Y = ones([m,n]);
x = ones([n,m]);
e = exp(1);
Z = [cos(x)*cos(sqrt(X.^2 + Y.^2))]*e.^-abs(2*x);
