MATLAB function for normalising an image matrix between [X;Y]

normaliseXY.m

function normalised = normaliseXY(array, x, y)

     % Normalize to [0, 1]:
     m = min(array(:));
     range = max(array(:)) - m;
     array = (array - m) ./ range;

     % Then scale to [x,y]:
     rangeXY = y - x;
     normalised = (array*rangeXY) + x;
