Bug 285

Summary: Compute only one half of a Sparse*Sparse product
Product: Eigen Reporter: Christoph Hertzberg <chtz>
Component: SparseAssignee: Nobody <eigen.nobody>
Status: NEW ---    
Severity: enhancement    
Priority: ---    
Version: 3.0

Description Christoph Hertzberg 2011-06-03 12:25:59 UTC
When computing a product A.transpose() * A, it is often sufficient just to compute the upper or lower half. This would also increase the performance of iterating over the diagonal of the result.
Similar to bug 284 this can be useful for non-linear optimization algorithms.
