MATLAB has no tools for HSI or HSL. There are tools on the File Exchange. The ones I use are here:
There are also others on the File Exchange, though be aware that Pascal Getreuer's popular Colorspace Transformations has a bug in the HSI path and will give the incorrect results unless you use the .mex version.
