#3396: add a sparse_view class that wraps pre-allocated data into a matrix
expression
------------------------------+---------------------------------------------
Reporter: guwi17 | Owner: guwi17
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
