Hi!
I want to create a new color scale that will be used for mapping to a grayscale picture.
I have three equations for RGB values calculated by linear interpolation with 256 steps scale, but I cannot find the way to calculate it on MATLAB.
Any suggestion would be greatly appreciated.

Make an N by 3 array. So
x = (0:255)';
redMap = your red formula.
greenMap = your green formula
blueMap = your blue formula
cMap = [redMap(:), greenMap(:), blueMap(:)];
colormap(cMap);
