Compute 2D partial derivatives for surface data

Source: R/extendr-wrappers.R
fdata_deriv_2d.Rd

For a surface f(s,t), computes:

  • ds: partial derivative with respect to s (∂f/∂s)

  • dt: partial derivative with respect to t (∂f/∂t)

  • dsdt: mixed partial derivative (∂²f/∂s∂t)

Usage

fdata_deriv_2d(data, argvals_s, argvals_t, m1, m2)

Details

Data layout: n surfaces, each stored as m1m2 values in row-major order (s varies fastest) Return: list with three matrices (ds, dt, dsdt), each n x (m1m2)
