Module differentiate 

Numerical differentiation (finite differences). Numerical Differentiation — deterministic finite-difference routines.

Determinism Contract

All routines produce bit-identical results for the same inputs. No floating-point reductions are performed (each derivative estimate is a single arithmetic expression), so no accumulator is needed.

Functions

• [diff_central] — central difference derivative estimates at interior points
• [diff_forward] — forward difference derivative estimates
• [gradient_1d] — numerical gradient of uniformly-spaced data

Functions

diff_central

Central difference approximation of the derivative.

diff_forward

Forward difference approximation of the derivative.

gradient_1d

Numerical gradient of uniformly-spaced 1D data.
