Creates a unique_ptr to a Kernel object, which can be GaussKernel, LaplaceKernel, ... .
scalar_t | the scalar type to represent the kernel. |
k | Type of kernel |
args | arguments to be passed through to the constructor of the actual kernel (fi, data, h, lambda for GaussKernel) |
|
inline |
Return a string with the name of the kernel type.
|
inline |
Return a KernelType enum from a string. If the string is not recognized, a warning is printed and the GAUSS kernel type is returned.
