I would like to know how to do a loop to extract all the columns from a matrix and generate individual vectors
Thanks to all

What are you going to do with the individual vectors when they are no longer in the matrix?
Almost certainly anything you want to do would be better off having them all within the matrix and run whatever your vector-based operation is in a for loop if it cannot be vectorised.

I would like to use the cftool and dependent variables in my fits are in matrix columns
Many thanks

If you have a matrix, M, you can access column i (as a vector) by using M(:, i).
(The colon indicates 'every row')

Thanks Chris, this I know, but I would like to use a loop for doing it in one go for all the columns...if this is possible
