I agree Artur. I was recently in need for a resample without replacement function. I have not check your code but I had a look on what I did and it could be a refinement (following also Sven's answer). Say a matrix A is nxm. set k<=m. rvec = ranking( mrandgen(u,0,1,m,1) )' A=[,rvec[1:k]] (keeps k randomly selectled columns of A) I would like to see such a function in extra.gfn Yiannis -- ************************************************************************************************** Ioannis A.
