Hello,
I have read through all the trouble shooting advice on this website for the above error. I have attached my code, and I am not sure what I am doing that is causing this error.
Could somebody guide me what I am doing wornk?
Thanks.
function [] = Plot3D(cellArray,charArray)
x = linspace(-15,15,100);
y = linspace(-15,15,100);
[xx,yy] = meshgrid(x,y);
z = (sin(sqrt(xx .^2 + yy .^2)))/(sqrt(xx .^2 +yy .^2));
switch charArray
case 'surfc'
surfc(xx,yy,z);
xlabel(cellArray{2});
ylabel(cellArray{4});
zlabel(cellArray{6});
case 'surf'
surf(xx,yy,z);
grid on;
title("This is the surf:");
case 'contour'
grid on;
contour(xx,yy,z,'ShowText','on');
axis([-15 15 -15 15 -15 15]);
otherwise
subplot(2,2,1);
surfc(xx,yy,z);
subplot(2,2,2);
surf(xx,yy,z);
subplot(2,2,[3,4]);
contour(xx,yy,z);
end

Hi!
Please, share the error. And if possible, share cellArray and charArray.
Thanks

As per my understanding, you are trying to make different figures using surfc, surf, contour, and plot3, where the provided code's execution is leading to warnings.
You can overcome the warnings by utilizing element-wise division instead of regular division when calculating the variable 'z.' The updated code line would look as follows:
z = (sin(sqrt(xx .^2 + yy .^2)))./(sqrt(xx .^2 +yy .^2));
I hope it helps.
