yes，may be check the resHSV value，such as

resHSV = rand(10, 3)

resHSV = 10×3

0.7587 0.7579 0.0652 0.4818 0.0649 0.8844 0.0645 0.1354 0.6241 0.3727 0.3020 0.4130 0.3200 0.7897 0.9591 0.1881 0.8734 0.0345 0.5663 0.9280 0.7975 0.1788 0.2104 0.1991 0.9820 0.2493 0.1922 0.7460 0.6177 0.9019

size(resHSV)

ans = 1×2

10 3

rgb = hsv2rgb(hsv);
surf(peaks);
colormap(rgb);
