class  Isai
 The Incomplete Sparse Approximate Inverse (ISAI) Preconditioner generates an approximate inverse matrix for a given square matrix A, lower triangular matrix L, upper triangular matrix U or symmetric positive (spd) matrix B. More...
 
class  Jacobi

Enumeration Type Documentation

◆ isai_type

This enum lists the types of the ISAI preconditioner.

ISAI can either be generated for a general square matrix, a lower triangular matrix, an upper triangular matrix or an spd matrix.
