矩阵A支持HYPRE 的ParCSR格 式、PETSc 的矩阵形式和ISIS++ Row的矩阵形式。由于M是非对称的 (即使A 是对称的),因此不适合作为对称矩阵的迭代法(如CG)的 预条件子; Euclid是一种扩展性能较好的并行不完全LU分解(ILU)预条件子, 它支持各种ILU(k)和 ILUT, 包括块Jacobi ILU(k),并行ILU(k), 它比块Jacobi...

目前Hypre支持的存储形式为HYPRE_PARCSR,矩阵类为HYPRE_IJMatrix,和HYPRE_IJVector,经过print打出之后为“行,列,值”的坐标对。矩阵赋值支持按行赋值 HYPRE_IJMatrixSetValues(ij_matrix,nrows,ncols,rows,cols,values);// 其中,ij_matrix为矩阵地址,nrows是赋值的行数,ncols为该行非0元素个数,rows为行坐标,...
