Hi all, Greatly appreciate the comments about boxing last week. It solved my problem.
I have one more question ( maybe too simple) about a certain form of matrix multiplication ( i think its point to point?) Anyway say I have data matrix dat where: dat= 0 1 1 0 0 0 1 1 how can I multiply say 3 2 by every row. Resulting in the following matrix: dat = 0 2 3 0 0 0 3 2 I thought that this form of multiplication was done with +/.* but I am getting domain errors. Apologies about the simplcity of this question but its driving me mad!!
