)
Visual Basic (Declaration)
Public Shared Function Subtract ( _
	a As Double, _
	A As DoubleSymBandMatrix _
) As DoubleSymBandMatrix

Parameters

a
Type: System..::.Double
A scalar.
A
Type: CenterSpace.NMath.Matrix..::.DoubleSymBandMatrix
A banded matrix.

Return Value

A banded matrix, B, with the same upper and lower bandwidths as A, and B[i,j] = a - A[i,j] whenever j - i is less than or equal to the upper bandwidth of A, or i - j is less than or equal to the lower bandwidth of A.
