st: concatenating column vectors |

Date |

I want to calculate something for each column and concatenate them into a matrix. For a 3x3 matrix, for example, it can be done as follows: matrix Q=uu`i' /* this is directly from the code I'm using, In fact, I'm trying to modify a code provided by an individual*/ matrix Z=vecdiag(Q) matrix P=(Q[1...,1]/Z[1,1],Q[1...,2]/Z[1,2],Q[1...,3]/Z[1,3]) And I want to generalized this to NxN case, with and without using a loop both (since it looks like the use of a loop conflicts with some other part of the code, hence generates an error). How can this be done? Please advise. Many thanks, Jason * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
