Hello,

I am looking for a C++ library that has routines for a variety of complex matrix decompositions (eigen, cholesky, singular value etc) and even complex matrix inverse, principal matrix logarthm of a complex matrix etc.  And the matrices which I am talking are pretty huge..can go upto 1024 x 1024 x 32. [snip] I'm not positive if Eigen would fulfill your requirements, but it is

Hi Brian,

Based on:

 1024 x 1024 x 32

from Ramesh's post, I'm assuming he needs something more than a 2D array, and at least a 3D arraay; however, based on a quick look at:

http://eigen.tuxfamily.org/dox/QuickRefPage.html#QuickRef_Types

it appears Eigen only supplies 2D arrays.

Ah, but the types held by the 2D matrix can be vector types. I'm unsure how a 3D matrix would work without knowing special information about each 2D element in any case.
