Quick update. Following Serge, I managed to get from the HEX code to RGB via the following, avoiding the issue of the submatrix incorrectly defined.
rgb=[part(Hex_colour,1:2),part(Hex_colour,3:4),part(Hex_colour,5:6)]; for i = 1:size(rgb,1) red(i)=hex2dec(rgb(i,1)); green(i)=hex2dec(rgb(i,2)); blue(i)=hex2dec(rgb(i,3)); RGB_colours=cat(2,red,green,blue); end On Tue, 3 Oct 2023 at 12:42, Lester Anderson <arctica1...@gmail.com<mailto:arctica1...@gmail.com>> wrote: Hello Thanks for the suggestions. The 'part' option worked but the function fails at hexrgb=strsplit(x(i),[2 4])'; strsplit: Wrong size for input argument #1: A single string expected. This was the issue I was having initially, logically it should work, but looks like it just sees x as a whole.

The vector consists of HEX values for colours. I created a simple function to get RGB values. function rgb=hex2rgb(x) // x=string input hexrgb=strsplit(x,[2 4])'; rgb=hex2dec(hexrgb); endfunction --> HEX HEX = "FFFFFF" "D9FFFF" "CC80FF" "C2FF00" "FFB5B5" "909090" "3050F8" "FF0D0D" "90E050" "B3E3F5" etc The function works fine with single values as that is what strsplit expects, but not sure how to make it run through the string vector; indexing causes issues. Any pointers would be helpful.
