Abstractmatrix{t} and the immutable type myhierarchicalmatrix, endowing it with fields of hierarchicalmatrixblocks, lowrankmatrixblocks, matrixblocks, and a matrix of integers, assigned, to determine which type of block is.
Hierarchical Solvers Is An Approximate Sparse Direct Solver, Written Entirely In Julia.
Therefore, both the cpu time and memory requirement are reduced. The algorithm uses oðlognþ applications of the matrix on structured random test vectors and oðnlognþ extra computational cost, where n is the dimension of the unknown matrix. Pdf (1590 kb), ps ziped (849 kb) abstract:
