.SH NAME
tmp_fmm - returns the work space needed by fmm.
.SH SYNOPSIS
.TP 24
int tmp_fmm ( int m, int n, int k, double alpha, double beta )
.SH PURPOSE
tmp_fmm  returns the work space needed by fmm which 
performs to computation

C := alpha*op( A )*op( B ) + beta*C,

where  op( X ) is one of
.br

   op( X ) = X   or   op( X ) = X' (transpose of X),
.br

alpha and beta are scalars, and A, B and C are matrices, with op( A )
an m by k matrix,  op( B )  a  k by n matrix and  C an m by n matrix.

This routine has a C calling interface.  It can be used to determine
the exact amount of memory needed by fmm.

.SH PARAMETERS
.TP 8
m       - int.
On entry,  m  specifies  the number  of rows  of the  matrix
op( a )  and of the  matrix  c.  m  must  be at least  zero.
Unchanged on exit.
.TP 8
n       - int.
On entry,  n  specifies the number  of columns of the matrix
op( b ) and the number of columns of the matrix c. n must be
at least zero.
Unchanged on exit.
.TP 8
k       - int.
On entry,  k  specifies  the number of columns of the matrix
op( a ) and the number of rows of the matrix op( b ). k must
be at least  zero.
Unchanged on exit.
.TP 8
alpha   - double.
On entry, alpha specifies the scalar alpha.
Unchanged on exit.
.TP 8
beta    - double.
On entry,  beta  specifies the scalar  beta.  When  beta  is
supplied as zero then C need not be set on input.
Unchanged on exit.
.TP 8
return value - integer.
On exit this is the number of double words of temporary space needed
by fmm.
