Module Procedures

private elemental function bspline_4d_constructor_empty() result(me)

It returns an empty bspline_4d type. Note that INITIALIZE still needs to be called before it can be used. Not really that useful except perhaps in some OpenMP applications.

Arguments

None

Return Value type(bspline_4d)

private pure function bspline_4d_constructor_auto_knots(x, y, z, q, fcn, kx, ky, kz, kq, extrap) result(me)

Constructor for a bspline_4d type (auto knots). This is a wrapper for initialize_4d_auto_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(:) :: y

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

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

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

(nx,ny,nz,nq) matrix of function values to interpolate. fcn(i,j,k,l) should contain the function value at the point (x(i),y(j),z(k),q(l))
integer(kind=ip), intent(in) :: kx

The order of spline pieces in ( ) (order = polynomial degree + 1)
integer(kind=ip), intent(in) :: ky

The order of spline pieces in ( ) (order = polynomial degree + 1)
integer(kind=ip), intent(in) :: kz

The order of spline pieces in ( ) (order = polynomial degree + 1)
integer(kind=ip), intent(in) :: kq

The order of spline pieces in ( ) (order = polynomial degree + 1)
logical, intent(in), optional :: extrap

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

Return Value type(bspline_4d)

private pure function bspline_4d_constructor_specify_knots(x, y, z, q, fcn, kx, ky, kz, kq, tx, ty, tz, tq, extrap) result(me)
