This function returns a vector of length n with the evaluation of an exponential Kernel at a point x0
\in R^2 for the n Fourier frequencies.

This function returns a vector of length n with the evaluation of an exponential Kernel at a point x0
\in R^2 for the n Fourier frequencies. In particular the k-th vector element is
e^{-\frac{(\boldsymbol{ω}_k - x_0)^T(\boldsymbol{ω}_k - x_0)}{h^2}}.
It returns a list containing the following component:
v |
vector containing the n exponential Kernel evaluations. |
It is auxiliary for locmulti
, grad
and hess
functions.
