Warning: Matrix is singular to working precision.

This is my code and I keep getting the error "Warning: Matrix is singular to working precision." I am getting extremely frustrated because i looked up the problem and my code seems to be correct but i am new to this so i could be missing something. Any help would be appreciated! Thank you! :)

x=(-pi:pi/10:pi);
y=(-pi:pi/10:pi);
[X,Y]=meshgrid(x,y)
Z=(sin(sqrt(X.^2+Y.^2)))/(sqrt(X.^2+Y.^2));
mesh(X,Y,Z)
xlabel('x-axis')
ylabel('y-axis')
zlabel('z-axis')

Answer 1

[James Tursa]

Z=(sin(sqrt(X.^2+Y.^2)))./(sqrt(X.^2+Y.^2)); % changed / to ./

The ./ is element-wise division, whereas the / implies the equivalent of linear algebra matrix inversion.
