numdifftools 0.9.12

'Solves automatic numerical differentiation problems in one or more variables.'

Suite of tools written in _Python to solve automatic numerical differentiation problems in one or more variables. Finite differences are used in an adaptive manner, coupled with a Richardson extrapolation methodology to provide a maximally accurate result. The user can configure many options like; changing the order of the method or the extrapolation, even allowing the user to specify whether complex-step, central, forward or backward differences are used.

The methods provided are:

• Derivative: Compute the derivatives of order 1 through 10 on any scalar function.

• Gradient: Compute the gradient vector of a scalar function of one or more variables.

• Jacobian: Compute the Jacobian matrix of a vector valued function of one or more variables.

• Hessian: Compute the Hessian matrix of all 2nd partial derivatives of a scalar function of one or more variables.

• Hessdiag: Compute only the diagonal elements of the Hessian matrix

All of these methods also produce error estimates on the result.
