I'm porting MATLAB code into C++, but I have a problem.

In the MATLAB source, there is a statement like this.

C=atan2(-A,B)

where A and B are matrices.

How can I write this in C++ using Eigen?

indeed, we don't offer an atan2 method yet. You can still do:

using std::atan2;

-A.binaryExpr(B, std::ptr_fun(atan2))

Oh... Thanks.
I didn't notice binaryExpr function.
It worked.
