bspline_1d_constructor_specify_knots Function

private pure function bspline_1d_constructor_specify_knots(x, fcn, kx, tx, extrap) result(me)

Constructor for a bspline_1d type (user-specified knots). This is a wrapper for initialize_1d_specify_knots.

Arguments

Type IntentOptional Attributes Name
real(kind=wp), intent(in), dimension(:) :: x

(nx) array of abcissae. Must be strictly increasing.
real(kind=wp), intent(in), dimension(:) :: fcn

(nx) array of function values to interpolate. fcn(i) should contain the function value at the point x(i)
integer(kind=ip), intent(in) :: kx

The order of spline pieces in ( ) (order = polynomial degree + 1)
real(kind=wp), intent(in), dimension(:) :: tx

The (nx+kx) knots in the direction for the spline interpolant. Must be non-decreasing.
logical, intent(in), optional :: extrap

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

Return Value type(bspline_1d)
