Hello,
I have begun using arrays of complex numbers in Eigen (i.e. ArrayXcd). I see .real(), .imag() and .abs() methods, but I can't see a corresponding .arg() method to get the element-wise complex argument/phase/angle. I have fallen back to using (on a complex array called data):

Code: Select all

data.imag().binaryExpr(data.real(), ptr_fun<double,double,double>(atan2))

But this is rather clumsy. Am I missing an obvious better way or is this functionality missing from Eigen at the moment?
Thanks in advance.

Right, we should add both atan2 and arg shortcuts.

I updated bug 80 on bugzilla with these functions; see http://eigen.tuxfamily.org/bz/show_bug.cgi?id=80
