Yes. See the File Exchange contribution "video_fig" for an example of what can be done.

MATLAB: Extracting Data from Scope saved as figure, FIG file

1) Open the scope window from with your Simulink model.

2) Select File > Print to Figure. A Figure window will appear.

3) Select File > Save As> Save as a figure, FIG file.

4) Enter the following from the MATLAB Command Window or script

4.a)Open the figure, 'scope_figure', using the function 'openfig':

>> fig = openfig('scope_figure');

4.b) Next open the current axes:

>>ax = fig.CurrentAxes

4.c) Access the Current Axes Children:

>> g_array = ax.Children

4.d) This yields a graphics array containing your data. Access the data by:

>> x1 = g_array(1).XData
>> x1 = g_array(1).YData

MATLAB: Reduce the size of figure,

Then you are looking for some clever matrix work, rather than figure size.

Try smth like this:

wavelength = 100;
a = 1:4001;
A = repmat(a, [3001 1]);
B = 3.*(sin((1-A).*2.*pi./wavelength))  + 1003;
figure;
imagesc(B);

Takes less than a second to run on my computer and does around the same. You might have to fix the last couple of details for it to be an exact match.
