PaperSize In Normalized PaperUnits

Hello.

I am attempting to dynamically set the paper size based on the size of the data I have in a matrix. For example, if I had data that was 512x1024, I would want the paper size to be 1:2 relative to some unit (say an inch). In order to accomplish this generically, I want to use normalized paper units, like so:

>> set(gcf, 'PaperUnits'  , 'Inches')

>> get(gcf, 'PaperSize')

ans =

      8.5000   11.0000

>> set(gcf, 'PaperSize', [1, 1])

>> get(gcf, 'PaperSize')

ans =

       1     1

>> set(gcf, 'PaperUnits', 'Normalized')

>> set(gcf, 'PaperSize', [0.5, 1])

>> set(gcf, 'PaperUnits', 'Inches')

>> get(gcf, 'PaperSize')

ans =

     10.0000   11.2500

If I correctly understand how normalized paper units work, why in the end isn't the size set to 0.5:1 inch?

Thanks for your help.

set(gcf, 'PaperUnits', 'Normalized')
set(gcf, 'PaperSize', [0.5, 1])
get(gcf, 'PaperSize')

The setting of the paper size is ignored. In normalized units the paper size is always [1, 1]. I don't know how MATLAB converts from normalized to inches for the paper size.

Why not just do:

set(gcf, 'PaperUnits', 'Inches')
set(gcf, 'PaperSize', [0.5, 1]*InchesPerUnit)
get(gcf, 'PaperSize')

with InchesPerUnit being the conversion from normalized paper to inches.

That workaround that appears to do the trick, though I still don't understand why the paper size would get set to 10 x 11.25 after changing it in normalized units.

Thanks for your help.
