[eigen] Optimization for special complex operations

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]

Hi everyone again. Lately I've been using Eigen with complex numbers to calculate things such as calculating the maximum of the real part or imaginary part of a certain vector. I suppose that trying to take the real part and then use maxCoeff() or minCoeff() would create a possible unnecessary temporary.

Another thing is to be able to do something like:

MatrixXf nn,xx;
xx = nn.colwise().normalized();

Here there are two very different concepts:

Does this make sense? I would like to work on these but I don't want to introduce code that would not make sense or break rules. I only have a small insight of what eigen looks like inside.
