When I test this code:

error : sls = shearletSystem('ImageSize',[numRows numCols],'FilterBoundary','truncated');

Undefined function or variable 'shearletSystem'.

[numRows,numCols] = size(circleGS);
sls = shearletSystem('ImageSize',[numRows numCols],'FilterBoundary','truncated');
[psi,scale,shear,cone] = filterbank(sls);

load mask
[numRows,numCols] = size(circleGS);
sls = shearletSystem('ImageSize',[numRows numCols],'FilterBoundary','truncated');
[psi,scale,shear,cone] = filterbank(sls);

Try this way by adding 'load mask' command above. If something goes check your circleGS matrix. It should work.

@Walter Roberson Windows 7 no ?

I just checked a technical reference, and it appears that I might have been mistaken. According to what I am looking at now, you would need Windows XP, not the later Windows Vista.

Windows 7 is out of the question, not possible for that installation process.
