I have a meshed annular region (shown in image), I have no a analytical function z=f(x,y）but a matrix A stored z value of each node. furthermore, I know coordinates of every element in A matrix. Now, I want to plot the plot of z in this annular region. I know if the refion is rectandle, this is easy to do using mesh or surf. Anyone can help me? Tanks firstly.qw.jpg

YOu can use surf for this. Convert your polar coordinates to cartesian using pol2cart. If not attach your data.

Hi,
I understand that you are trying to plot a 3D surface using a matrix in Polar coordinate. You can refer this link to find the detailed way to plot a 3D surface in a polar coordinate.
