#ifndef GRAPHMATPLUSPLUS_H
#define GRAPHMATPLUSPLUS_H

// Revision 1.5  2005/02/28 17:21:12  klamer
// Changed to have g++ 3.2.3 run silently using g++ -ansi -pedantic -Wall -Wno-unused -Wno-reorder.
// Change use of (libg++) String to ANSI C++ string.
//
// Revision 1.5  1993/05/13  12:50:59  klamer
// fixed v2 -= v2 to use vv_sub2 instead of vv_add2
// added -v3, v3 * s, s * v3, v3 + v3, v3 -= v3
//
// Revision 1.4  1993/01/18  16:23:47  klamer
// Added m3 * m3, m3 * v3 and v3 - v3.
//
// Revision 1.3  1992/10/20  11:02:52  klamer
// Added operator versions of:
// double * hvec2
// hvec2 / double
// hvec2 += hvec2
// hvec2 -= hvec2
// hvec2 *=double
// hvec2 /= double
