how to make irregular 3d shape with spherical coordinates?

Hi, I have some different values of 'r' in spherical coordinates and want to plot 3d irregular surface. e.g, I have phi = [0,2pi] and theta = [0,pi/2], so for each phi and theta, I have different r value. I just want to plot the surface, with no color, and only showing the variation in r by 3d surface.

Attaching a sample code. I have converted the spherical coordinates to Cartesian, keeping radius variable as a vector. Further I have used surf function for the 3d plot.

Thanks @Vineeth Nair... It is good.. but I want actually a sphere with different radius,,, Means from some points it will be inside and from some it will be out,, like connecting point of spherical coordinates with ir-regular radius. Thanks for your solution. Highly appreciated.

how can i plot this map in matlab or python ?/

x=lat : utm system

y= long

z= magnetic data
