Hi,

I understand that you are facing an issue while drawing a sphere in 3D.

To draw a sphere, you should use the “ezsurf” function as mentioned below:

ezsurf('cos(u).*sin(v)', 'sin(u).*sin(v)', 'cos(v)', [0, 2*pi, 0, pi])

The above command plots a sphere of radius "1" centered at the origin by parametrizing the sphere using spherical coordinates. The first argument corresponds to the x-coordinate, the second argument corresponds to the y-coordinate and the third argument corresponds to the z-coordinate.The ranges for "u" and "v" are specified as [0, 2*pi] and [0, pi] respectively, to cover the entire sphere.

For more information regarding "ezsurf" function, kindly refer to ezsurf function.

I hope this answer resolves the issue you are encountering.
