Ubaashana - in the (save) push button callback, you will save the data to file, possibly using imwrite. For example,

 function pushbutton1_Callback(hObject, eventdata, handles)

 % get the image data to save (from an axes or the handles structure)
 imgToSave = ...;

 % save to file
 filename = ...;
 imwrite(imgToSave, filename);

I'm assuming that you can easily get the watermarked image from the handles structure and that the filename is known (or are you asking the user for the filename?).

MATLAB: Load .mat file

Try this:

A = textscan(fid, '%s', 'Delimiter', ' ');
impData = A{1};  %%This cell contains your data
impData = impData (3:end); %%The data excluding the first two lines
strData = cellfun(@strsplit, impData, 'UniformOutput',0); %%Split data into two rows
numData = cellfun(@str2double, strData, 'UniformOutput',0); %%Convert to numeric values
matData = cell2mat(numData); %%Convert into a matrix
