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](https://www.mathworks.com/matlabcentral/answers/uploaded_files/219631/image.jpeg)

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