and I want to extract the values of each pixel and put them in a matrix form so I can work with them
What can I do?

Ran in:
Try this —
F = openfig('Example.fig'); % Load File & Display Contents
Ax = gca; % Get Axis Handle
Fmtx = Ax.Children.CData % Get Image Data
Fmtx = 15×15

Hi MementoMori,
According to me these commands will help you get the results
>>s=load('Example.fig','-mat'); %opening the figure
>> values=s.hgS_070000.children(1).children.properties.CData; %storing pixel values
>> fig = imagesc(values); %verifying by plotting the ‘values’ which are our pixel values
You can see the pixel values by double clicking on ‘values’ variable created in your workspace
You can refer to these documents also-
Hope it helps!
