subscript problem

I have a code as follows:

hsv=rgb2hsv(iOrg);

g=stdHue(hsv(:,:,1)*360);

where stdHue is a user defined function. but it shows me the following error.

 Subscript indices must either be real positive integers or logicals.

Error in ==> .............at 35

g=stdHue(hround);

Is there any one to help me?

Thanks

Either you redefined stdHue to be a variable in your code, or there is some reason that MATLAB does not know that stdHue is a function. (The latter situation an occur in some cases where functions are "poofed into existence".)
