I have a problem with generating "nice" c-code in mathematica.
When I use the packages "Format" and "Optimize" to generate the
c-code, the (integer) powers are coded as function calls instead of
multiplications (e.g. pow(x,2.) instead of x*x). These function calls
are obviously quite ineffective in many cases.
Here is a simple example of my problem:
CAssign[x^2, AssignOptimize -> False, OptimizePower -> Binary]
Mathematica Output: pow(x,2.)
Desired Output: x*x
I thought that the option "OptimizePower -> Binary" would be
sufficient to get an output of the form "x*x".
Is there another option that I should use in the CAssign call?
Or is there a better way of generating c-code from mathematica?
thanks in advance,
