First I think there is a problem with ccode doing what it is supposed to
do. Consider the following code -
(x,y,th) = symbols(r"x' y' \theta")
then
x' = ccode(x)
y' = ccode(y)
\theta = ccode(th)
I don't think x', y', and \theta are legal program variables in c.
Also I have looking at codegen examples and wish to know if the following
conclusion is correct. If I have a python function (example) -
def W(x):
s = 1
for i in range(10):
s += x**i
return s
there is no simple way (if any) to convert it to -
double W(double x)
{
double s = 1;
int i;
for (i=0;i<10;++i)
{
s = s+pow(x,i);
}
return s;
}
