Hi,

I am updating a matrix in a for loop. I want to freeze a particular column of this matrix, say column j, and update the rest of the matrix.

Any help would really be appreciated. Thanks.

Yes, that's exactly what I am doing now. I would have thought that maybe there exists an easier approach.

I guess it all depends on how you are updating your matrix. Can you post a short example?
