Function Documentation

std::complex<float> GCF::c_cbrt

(

std::complex< float >

x

)

Compute the cube root of a complex number.

Parameters

x	The complex number whose cube root is to be taken.

Returns

The complex cuberoot of x.

float GCF::hermite_interp	(	float	t,
		float	x1,
		float	x2,
		float	y1,
		float	y2,
		float	dy1,
		float	dy2
	)

Compute the hermite interpolation between two values.

This performs a hermite approximation of a function f. The approximation is a fourth-order (third degree) approximation derived from the values:

• y1 = f(x1)
• dy1 = f'(x1)
• y2 = f(x2)
• dy2 = f'(x2)

Parameters

t	The interpolant (lies in the range [0, 1].
x1	The first x-value.
x2	The second x-value.
y1	The first y-value (i.e., f(x1)).
y2	The second y-value (i.e., f(x2)).
dy1	The first derivative value (i.e., f'(x1)).
dy2	The second derivative value (i.e., f'(x2)).

Returns

The approximate value of the function.
