Exceptions
Exception | Condition |

ArgumentNullException | If an input parameters are NULL |
InvalidOperationException | If Interpolation object has been disposed before Apply() calls |
Remarks
X defines new positions for the interpolation based on the trained object state. The shape of X is not taken into account. If X is not a vector, its values are read in sequential order.
Interpolation values are computed from the original values V used to train this interpolator objects. The array returned will have the same shape as V, except the working dimension of V is replaced with n interpolated values, n = X.S.NumberOfElements. The 'working dimension' of V is 1 if V is a row vector, 0 otherwise.

Examples
// Define some sample points as a function: f(x) = sin(x); Array<fcomplex> X = linspace<fcomplex>(-pi, pi, 10); Array<fcomplex> V = sin(X); // Create Interpolator Object order 5 using (var interp = new LinearInterpolatorSingle(V, X)) { // Get some random scalar values fcomplex val1 = (fcomplex)interp.Apply(0.024); fcomplex val2 = (fcomplex)interp.Apply(-0.21); // Get 10 linear spaced values defined on range (-0.5, 1.25) Array<fcomplex> valRange = interp.Apply(linspace<fcomplex>(-0.5, 1.25, 10)); // Get 30 interpolated values using Xn query points defined as array[3 x 2 x 5] Array<fcomplex> Xn = counter(0.0, 0.1, 3, 2, 5); Array<fcomplex> Vn = interp.Apply(Xn); }
