dot-get_d2psf_dxdy: Calculates the mixed partial derivative: d^2 * z / dx * dy...
In AlexCast/apsfs: Monte Carlo code for simulation of atmospheric Point Spread Functions and spatially-resolved Spherical Albedo Functions
.get_d2psf_dxdy R Documentation
Calculates the mixed partial derivative: d^2 * z / dx * dy for a scalar
valued function (z) of two arguments (x, y). This is the bidimensional
density function, the underlying process integrated by Monte Carlo,
sub-sequentially used to calculate the bidimensional cumulative
distribution function fitted by fit_sectorial or fit_grid.
Description
The code is modified from numDeriv:::genD. The original function is generic
and vectorized in the sense of a vector valued function. It was adapted here
to solve a scalar valued function at several coordinates at the same time for
reasons of computational efficiency. The modifications below make this
function specific to the problem at hand, in particular the way the
predict_sectorial subfunctions are expected to work.
Usage
.get_d2psf_dxdy(func, x1, x2, ...)
Details
It is based on the numDeriv R package source code version 2016.8-1.1, that is
licensed under GPL-2. This package is also licensed as GPL-2 and a copy of the
license is provided in the root directory of the package. Modifications made
