PatternRange.h
Range/Iterator types associated with Pattern.

myra::Pattern
Holds the nonzero pattern of a sparse matrix.
Definition: Pattern.h:55

myra::PatternBuilder
Like Pattern, but easier to populate via insert()/erase() methods.
Definition: PatternBuilder.h:51

Pattern.h
Container class for a sparse nonzero pattern, used in reordering/symbolic analysis.

myra::Natural2D
A helper class that generates a natural ordering on a 2D structured grid of size IxJ.
Definition: laplacian2.h:43

laplacian2.h
Helper routines for reordering/filling 2D structured grids. Used by many unit tests.
