MATLAB: How to normalize values in a matrix to be between 0 and 1

Question

I have a matrix Ypred that contain negative values and I want to normalize this matrix between 0 and 1

 Ypred=[-0.9630 -1.0107 -1.0774
       -1.2075 -1.4164 -1.2135
       -1.0237 -1.0082 -1.0714
       -1.0191 -1.3686 -1.2105];

I'm new in matlab, please help me, there is a matlab function or toolbox that can do this? thanks

Answer 1

This can be simply done in a two step process

1. subtract the minimum
2. divide by the new maximum

normA = A - min(A(:))
normA = normA ./ max(normA(:)) % *

note that A(:) makes A into a long list of values. Otherwise min(A) would not return a single value ... Try fro yourself!
