     Type:  Feature Requests  |      Status:  new           
Milestone:  Boost 1.41.0      |   Component:  uBLAS         
  Version:  Boost 1.40.0      |    Severity:  Not Applicable
 Keywords:                    |  
------------------------------+---------------------------------------------
 Provide a way to use ublas with pre-allocated data. Implement a matrix
 view of a CRS matrix as proof of concept. Details:

 * given 3 arrays: row pointers, column indices, values
 (http://www.netlib.org/utk/papers/templates/node90.html)

 * provide a wrapper that fulfills the immutable part of the matrix
 expression

 Further tasks:

 * split the current matrix and vector concepts into immutable and mutable
 parts in order to gain a "read-only view" concept and a full featured
 "expression" concept

 * improve traits mechanism and apply it where possible to automatically
 see a fixed size C-array as vector view or matrix view

 * add necessary tests
