	Gradient with respect to the parameters. Only exists after interpolate has been run.

Detailed Description

Interpolator is an uninstantiable protected class that retains common functionality between the MatrixInterpolator and VectorInterpolator classes. The interpolation algorithm was adapted from "Gradient-based Constrained Optimization Using a Database of Linear Reduced-Order Models" by Y. Choi et al.

Parameters

[in]	parameter_points	The parameter points.
[in]	rotation_matrices	The rotation matrices associated with each parameter point.
[in]	ref_point	The index within the vector of parameter points to the reference point
[in]	rbf	The RBF type ("G" == gaussian, "IQ" == inverse quadratic, "IMQ" == inverse multiquadric)
[in]	interp_method	The interpolation method type ("LS" == linear solve, "IDW" == inverse distance weighting, "LP" == lagrangian polynomials)
[in]	closest_rbf_val	The RBF parameter determines the width of influence. Set the RBF value of the nearest two parameter points to a value between 0.0 to 1.0
