get_knots_1d Subroutine

private pure subroutine get_knots_1d(me, tx, iflag)

Returns the knot vectors of a bspline_1d.

Type Bound

bspline_1d

Arguments

Type IntentOptional Attributes Name
class(bspline_1d), intent(inout) :: me

the spline
real(kind=wp), intent(out), dimension(:), allocatable :: tx

the (nx+kx) knots in the direction
integer(kind=ip), intent(out) :: iflag

status flag: 0 if no errors, 1 if the class is not initialized
