Detailed Description

Abstract operation for evaluating a partial derivative of a linear combination of basis functions.

The "naive" is indicating that classes implementing this operation should use a "naive" approach, e.g. by evaluating all basis functions by brute force.

Parameters

	alpha	coefficient matrix (each column is a coefficient vector)
	point	evaluation point
	derivDim	dimension in which the partial derivative should be taken (0, ..., d-1)
