在MATLAB平台下，如何画三维极坐标图。 源码以及说明-3D-polar plot function in matlab but it is not included in MATLAB HELP

POLAR3D Plots a 3D polar surface. POLAR3D(Zin,theta_m ax,Rho_min,Rho_max,meshscale) plots the profiles a mesh plot for Zin between radii Rho_min and Rho_max for polar angles equally spaced between theta_min and theta_max. POLAR3D(Z
