	f As Double(,),
	xi As Double,
	yi As Double

	f As Double(,),
	xi As Double,
	yi As Double

public:
static double interp2(
	IList<double>^ x, 
	IList<double>^ y, 
	array<double,2>^ f, 
	double xi, 
	double yi
)

public:
static double interp2(
	IList<double>^ x, 
	IList<double>^ y, 
	array<double,2>^ f, 
	double xi, 
	double yi
)

Parameters

x: Type: System.Collections.Generic IList Double
The known independent values

y: Type: System.Collections.Generic IList Double
The known independent values

f: Type: System Double
The known dependent values

xi: Type: System Double
x value to at which to interpolate

yi: Type: System Double
y value to at which to interpolate

Return Value

Type:

Double
The interpolated value (clamped to boundary values if xi are of range)

Remarks

Assumptions: 1) x and y are monotonically increasing, and 2) xi and yi are inclusive to x and y respectively for interpolated results, otherwise return NaN
