How to retrieve the array matrix from .fig file

Hi,

I have did some coding in m-file to run the pcolor data plot type. Then, I save it as .fig file. That pcolor data plot consists of 128x128 array matrix. How can I retrieve the array matrix of 128x128 from .fig file that I saved? So that I can save it in workspace as .mat file.
