Convert Double Matrix To HSV in Matlab

I have a double matrix ​​in matlab and I want to convert it to an HSV image where supposedly similar double values ​​will appear with same color. I already converted to RGB with mat2gray but I want to to convert directly from double matrix to hsv image. Is it possible?

Thanks

You're asking if you can do what image and imagesc do. Yes, you can. You just need to interpolate into the 'hsv' colormap. The following code snippet demonstrates how to do this. It assumes your values are scaled between 0 and 1; you can easily change that though.

im = [0 .5 1; .7 .6 .2; .9 .3 .4];
cm = colormap('hsv');
cdata = interp1(linspace(0,1,length(cm)),cm,im);
figure;image(cdata)

cdata will be a (row x col x 3) matrix, you can use image directly to see it, or do whatever else you need to from there.
