How to normalize only one column of a matrix

Hi,

I need to normalize only one column (column 2 of my array X) of an array with 4 columns by rescaling the range of the data to the interval [0,1]. How to do this? I tried using the function below, but I wasn't successful.

Norm=normalize(X,2,'range');

normalize(X(:,2),'range',[0,1])

or simply

rescale(X(:,2))

If you want to replace the data in the matrix then allocate the function output, i.e.:

X(:,2) = ...
