I hate that I have to keep looking this up…
Here’s how to scale or normalize your numbers in MATLAB so they lie between 0 and 1.
Change the number of mins and maxs depending on the dimensionality of your matrix.
I = [ 1 2 3; 4 5 6]; % Some n x m matrix I that contains unscaled values. scaledI = (I-min(I(:))) ./ (max(I(:)-min(I(:)))); min(scaledI(:)) % the min is 0 max(scaledI(:)) % the max 1
All of scaledI values are now between 0 and 1.
