Can you try using the 'imwrite' function in MATLAB to convert a .MAT file to a .PNG image.
Here's an example:
load('yourFile.mat');
im = yourVariable; % substitute "yourVariable" with the name of the variable in your .MAT file
imwrite(im, 'yourFile.png');
Note that the input to the imwrite function should be a 2D or 3D matrix representing an image. If your .MAT file contains other data types, you'll need to extract the image data before passing it to imwrite.

Specifically, it should be a MxNx1 or MxNx3 array to be compatible with imwrite() directly. imwrite() will not accept a volumetric image directly.
