initialize_from_coefficients_1d_multi Subroutine

private pure subroutine initialize_from_coefficients_1d_multi(me, tx, bcoef, kx, iflag, extrap)

Initialize a bspline_1d type with multiple outputs directly from its knots and b-spline coefficients. The last dimension of bcoef is the output index.

Type Bound

bspline_1d

Arguments

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

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

The (nx+kx) knots in the direction.
real(kind=wp), intent(in), dimension(:,:) :: bcoef

(nx,nf) array of b-spline coefficients
integer(kind=ip), intent(in) :: kx

The order of spline pieces in

integer(kind=ip), intent(out) :: iflag

status flag (see initialize_from_coefficients_1d), or 6005 if bcoef has no outputs
logical, intent(in), optional :: extrap

if true, then extrapolation is allowed (default is false)
