SparseSolve(_:_:_:)

Solves the equation Subfactor * X = B in place for the matrix of double-precision values X, without any internal memory allocations.

Declaration

func SparseSolve(_ Subfactor: SparseOpaqueSubfactor_Double, _ XB: DenseMatrix_Double, _ workspace: UnsafeMutableRawPointer)

Parameters

  • Subfactor:

    The Subfactor in Subfactor * X = B that Sparsecreatesubfactor(_:_:) 49d8w returns.

  • XB:

    On input, the matrix B. On return, the matrix X overwrites it.

  • workspace:

    A workspace of size workspaceRequiredStatic + nrhs * workspaceRequiredPerRHS where nrhs is the number of right-hand-side vectors.
