Options

Below is a complete list of options that may be used in the numerical_solve function.

Option

Description

Format

Default value

method

We can choose the method to be used from the following: bisection, newton, regula_falsi, secant.

String. {method="bisection"}

By default, the best method is selected.

initial_point

The initial point for the numerical solver. When using secant, bisection or regula_falsi, two points need to be provided, and the function must have opposite sign in the those points.

A real number. {initial_point=1.0, method="newton"}.

By default, the best point is selected.

system_method

We can choose the method to be used for the system resolution from the following: broyden, newton and steffenson.

{system_method=”newton”}

{system_method="broyden"}

tolerance

We can choose the tolerance to be used.

{tolerance=10^{-8}}

{tolerance=10^{-12}}

result

We can choose the format of output of the solution.

{result="vector"}

{result="table"}
