integrate_range_re Function

public function integrate_range_re(x, y, a, b) result(r)

This function constructs a piecewise hermitian cubic interpolation of an array y(x) based on discrete numerical data, and subsequently evaluates the integral of the interpolation in the range (a,b). Note that the mesh spacing of x does not necessarily have to be uniform.

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=wp),	intent(in),		dimension(:)	::	x	Variable x

real(kind=wp),	intent(in)			::	a	Left endpoint
real(kind=wp),	intent(in)			::	b	Right endpoint

Return Value real(kind=wp)
