Subject   st: Extracting a scalar from a matrix
Date   Thu, 27 Nov 2003 09:33:05 -0500

I have a matrix (vector) of which I want to extract the first element as a scalar.
 
What I did is : matrix  alpha = beta[1,1]
 
The problem is that I need to use the extracted element (alpha) as a scalar rather than as a matrix.
 
Does anyone can help ?
