For trivial expressions, we don't need automatic code generation. For complicated expressions, code generator creates lots of temporary variables and the performance is not far from optimal. Once I generated a C program using codegen with 500+ temporary variables and I put that function into a numerical integral as an integrand. The result was very unstable - the integrals are often NaNs. On the other hand, I also convert Maple expression manually into C program which has exactly the same functionality. The result was correct, no NaNs in the integrals at all. So what's the use of code generation in Maple?
