Re^2: Counting PDL vectors in a PDL matrix

Hi,

Thanks for the quick replies all. Thanks to choroba for linking to uniqvec, which I must have missed during reading the documentation.

Thanks to vr for the good example code, this clears things up a bit. I came to the conclusion that my whole approach was incorrect (which I kind of expected when learning PDL).

I am building up the matrix vector by vector, so if we consider each vector as a single entity (which is what I am doing), then rather than a 2D matrix of vectors, in essence I have a 1D vectors of entities. Therefore, I am choosing to build the lookup table during creation.

Many thanks all.

A really good PDL library for operating on vectors is PDL::VectorValued. Indeed, it's so good that we're just discussing incorporating it into main PDL (see https://github.com/moocow-the-bovine/PDL-VectorValued/issues/5). The particular operation you'd want here is probably `vsearchvec`.	[reply] [d/l]
