Syntax
Parameters
- x
- Type: System..::.Double
A double scalar specifying the x-coordinate of
the evaluation point for the tensor-product spline.
- y
- Type: System..::.Double
A double scalar specifying the y-coordinate of
the evaluation point for the tensor-product spline.
- xPartial
- Type: System..::.Int32
An int scalar specifying the x-partial derivative.
- yPartial
- Type: System..::.Int32
An int scalar specifying the y-partial derivative.
Return Value
A
double scalar containing the value of the
partial derivative
where
i =
xPartial and
j =
yPartial, at
(x, y).
