[eigen] Multi Dimensional Arrays

[Andy Somogyi <andy.somogyi@xxxxxxxxx>]

Hello All,

I know this has been discussed on and off.

From what I understand, the only way to handle multi dimensional arrays with Eigen is something along the lines of

Array<Array<double,Dynamic,Dynamic> ,Dynamic, Dynamic> ...

This is really far from ideal as it really is an array of arrays (separate memory blocks).  Has there been any talk of merging in some multi dimensional support to Array, say from the now defunct blitz++ code, or adding it a new?

I really really really just want to use A SINGLE LIBRARY, and have to rely on Eigen for linear algebra, and boost multi-array or blitz++ for multi-dimensional arrays. What would be nice is to have a multi-dim array, be able to grab a dimension or sub-array out of it, and use it directly as an Eigen Array / Matrix.
