SparseMultiply(_:_:_:_:)

Performs the multiply operation Y = Subfactor * X on a dense matrix of single-precision values and without any internal memory allocations.

Declaration

func SparseMultiply(_ Subfactor: SparseOpaqueSubfactor_Float, _ X: DenseMatrix_Float, _ Y: DenseMatrix_Float, _ workspace: UnsafeMutableRawPointer)

Parameters

  • Subfactor:

    The subfactor to multiply by, which Sparsecreatesubfactor(_:_:) 4renf returns.

  • X:

    The matrix X.

  • Y:

    The matrix Y.

  • workspace:

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