Change order of columns in a matrix.

Hi there,
I have got a 17x265 doube matrix with name weights.
Each row has a sum of 100.
I changed the order of columns with a variable ind (1x265 double) with numbers ranging from 1 to 265 in a specific order (i.e. [5 6 265 210...]) with the following code:
weightsNew=weights(:,ind)
The thing is now: If I sum each row, the sum isn't 100 anymore.
Does the above mentioned code change the numbers of matrix weights when I change the order of rows and save it in weightsNew?

It is possible that ind has repeated/ missing indices, which could then change the row sums. If you upload the data then we can look at this. No data = very difficult for us to help you.
