Question: C CodeGeneration

Hi All,

I am working on modeling dynamics for a robot. It requires a write some long expressions into C++.  When I do it, it has some strange problem in creation of C++ code from a vector.

Here is an example of the problem. I have a multivariable polynomial term, I using coeffs to get its coefficients and corresponding unevaluated variables, which works fine. But I can't convert the vector into C++

Ca := coeffs(term, [W, Rf, Rr, dxf, rcf, rcr], 'L'):

L;                           Rf, Rr, dxf

C(L, resultname="L11", output="dSpDdx1.cpp");

Error, (in Translate) options [Rr, dxf] not recognized.

I don't know why maple thought the unevaluated variable Rr and dxf are options instead of the vector I want to convert into c++. Does any one know what I did wrong?

Thanks in advance.
