Classes

struct  block_interleaved_storage_scheme
 Defines the parameters of the interleaved block storage scheme used by block-Jacobi blocks. More...
 
class  Ilu
 The Incomplete LU (ILU) preconditioner solves the equation $LUx = b$ for a given lower triangular matrix L, an upper triangular matrix U and the right hand side b (can contain multiple right hand sides). More...
 
class  Isai
 The Incomplete Sparse Approximate Inverse (ISAI) Preconditioner generates an approximate inverse matrix for a given lower triangular matrix L or upper triangular matrix U. More...
 
class  Jacobi
 A block-Jacobi preconditioner is a block-diagonal linear operator, obtained by inverting the diagonal blocks of the source operator. More...

Enumeration Type Documentation

◆ isai_type

This enum lists the types of the ISAI preconditioner.

ISAI can either generate a lower triangular matrix, or an upper triangular matrix.
