If you're working in LAB and you want Hue and Chroma (i.e. the polar representations of the model you're already in) then I don't see the point in converting to HSV and calculating something unrelated.
If you want LCHab, simply convert your LAB representation into cylindrical coordinates, or simply use the cform tools in IPT.
rgbpict = imread('peppers.png');
labpict = rgb2lab(rgbpict); % you already have this
c = makecform('lab2lch');
lchpict = applycform(labpict,c);
There are other tools available on the File Exchange if you want to go straight from sRGB to LCHab and vice-versa.
