CSparse (Part of SuiteSparse)

Build Status

Currently, this package only contains the CSparse functions (etree, symperm, ereach and csc_permute) moved from Base Julia.

At some point the rest of the SuiteSparse functionality in Julia might be moved here.

Documentation

etree(A[, post])

Compute the elimination tree of a symmetric sparse matrix A from triu(A) and, optionally, its post-ordering permutation.

symperm(A, p)

Return the symmetric permutation of A, which is A[p,p]. A should be symmetric, sparse, and only contain nonzeros in the upper triangular part of the matrix is stored. This algorithm ignores the lower triangular part of the matrix. Only the upper triangular part of the result is returned.
