hip_smooth_step()

void hip_smooth_step	(	void *	x,
		real *	edge0,
		real *	edge1,
		int *	n
	)

Fortran wrapper for 2nd order smooth_step

Compute the smooth step function for a given array. t = clamp((x - edge0) / (edge1 - edge0), 0.0, 1.0); return t^3 * (t * (6.0 * t - 15.0) + 10.0);

		real *	left,
		real *	right,
		int *	n
	)

Fortran wrapper for step function

Compute the step function for a given array. if (x < edge) return left; else return right;

Parameters
