显示 更早的评论
hello everyone... i need a code to normalize( between 0 and 1) a matrix 7*50. the normalization process should be for each column not row**. in other words, the program should seek for the largest value in each column and divide all the elements in that column by it. can anybody help plzz

Assuming values are positive, e.g.,
M = your matrix
N = bsxfun(@rdivide,M,max(M)); % Normalized (scaled) matrix by column

rng('default')
A = 100*randn(3)
Amin = repmat(min(A),3,1)
Amax = repmat(max(A),3,1)
a = (A-Amin)./(Amax-Amin)
Hope this helps.
Thank you for formally accepting my answer
