matrix is singular to working precision , Contour not rendered for non-finite ZData

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

wrong*, sorry.

Hi!

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

Thanks

Hello,

This is the error:

Warning: Matrix is singular to working precision.

Warning: Contour not rendered for non-finite ZData

Warning: Matrix is singular to working precision.

Warning: Matrix is singular to working precision.

Warning: Contour not rendered for non-finite ZData

Warning: Matrix is singular to working precision.

Warning: Contour not rendered for non-finite ZData

Warning: Contour not rendered for non-finite ZData

And this is the code I am trying to run:

load('cellArray.ma'); % something that I load from my computer to see if the function working.

figure('Name', 'surfc')

Plot3D(cellArray, 'surfc')

figure('Name', 'surf')

Plot3D(cellArray, 'surf')

figure('Name', 'contour')

Plot3D(cellArray, 'contour')

figure('Name', 'abc')

Plot3D(cellArray, 'abc')

Thanks.
