  I would like to obtain Fortran source code for obtaining the outer
  product of two square matrices which may be of different size.
  This product is also called the tensor, Kronecker or direct product.
  
  The elements of the product matrix follow the so-called lexicographical
  ordering, the gist of which may be gathered from the abbreviated
  notation (where A and B are matrices):
  
             A (x) B =  A(1,1)B    A(1,2)B   ....
                        A(2,1)B    A(2,2)B   ....
                         ..         ..       ....
  Outer products of this sort provide a way of building higher-rank
  tensors from lower rank ones, and typical applications include coupling
  of spin angular momenta.
 
  Please reply via Email.  And thanks in advance.
