Usage
 
 Creates a sparse identity matrix of the given size.  The syntax for
 its use is
 
   y = speye(m,n)
 
 which forms an m x n sparse matrix with ones on the main diagonal,
 or
 
   y = speye(n)
 
 which forms an n x n sparse matrix with ones on the main diagonal.  The
 matrix type is a float single precision matrix.
