defines a kernel function as a function of the rotational angle
Wraps an arbitrary function of the cosine of the polar angle into an S2Kernel. Its Legendre coefficients are computed by quadrature unless they are passed in.
Syntax
psi = S2KernelHandle(fun)
psi = S2KernelHandle(fun,A)Input
| fun | @function_handle of cos(theta) |
| A | Legendre coefficients, computed by quadrature if omitted |
Output
| psi | S2Kernel |
Class Properties
| fun | the @function_handle |
| A | Legendre coefficients |
| bandwidth | maximum Legendre degree |
