trapz Function

public function trapz(x, y) result(Int)

Aproximates the integral of the function $$y = f(x)$$ given a set of points: $$(x_i,y_i)$$ using the trapezoidal rule. The points do not need to be linearly spaced along the integration domain.

Arguments

Type	Intent	Optional	Attributes		Name
real,	intent(in)			::	x(0:)	Array containing the abscissas of the points
real,	intent(in)			::	y(0:)	Array containing the ordinates of the points

Return Value real

Numerical aproximation to the integral
