Hello all,  

I have matrices V.i of dimension n.i x n.i, where i = 1, ..., J, and the sum of n.i equals N. (and n.i ! = n.j)  

goal: create one large matrix V, where V has matrices V.i on diagonal.  

I create each matrix V.i in a for loop (1 to J), so each time I'd like to augment V with the most recently calculated V.i, such that I'll have V after the final iteration of the for loop.  

question: how to initialize V and do the augmentation. any advice much appreciated.  


ps - please respond directly to afshar@miami.edu, thanks!
