New issue 1463 by Toon.Verstraelen: Initial codegen implementation
http://code.google.com/p/sympy/issues/detail?id=1463
I've tried to send the message below to sympy-patches, but it doesn't seem
to get through.
Hi,
This is my first attempt to use the sympy-patches list. The attached patch
is a proposal for the code generator for sympy, and includes working tests.
The current possibilities are intentionally very limited, but the code
should be extensible with future patches to handle the more complex cases
of interest.
The friendly interface is the codegen function, and works like this:
xyz = symbols("xyz")
codegen([("fn",(x+y)*z)], "C", "codegen")
This writes two files:
codegen.h:
/******************************************************************************
* Code generated with sympy
0.6.5-git *
*
*
* See http://www.sympy.org/ for more
information. *
*
*
* This file is part
of 'project' *
******************************************************************************/
#ifndef PROJECT__CODEGEN__H
#define PROJECT__CODEGEN__H
double test(double x, double y, double z);
#endif
codegen.c:
/******************************************************************************
* Code generated with sympy
0.6.5-git *
*
*
* See http://www.sympy.org/ for more
information. *
*
*
* This file is part
of 'project' *
******************************************************************************/
#include "codegen.h"
#include <math.h>
double test(double x, double y, double z) {
return z*(x + y);
}
The codegen function is based a more complex api with more possibilities.
More info can be found as comments and the doc strings. Any comments are
appreciated. (coding style, typo's, code design, milestones, ...)
cheers,
Toon
