                      Reading time: 1min

                      Solves numerically an equation or a system of equations.

                      Syntax

                      numerical_solve(Equation, ..., Equation)
                      

                      Description

                      Given an equation or system of equations, finds a solution using some numerical methods.

                      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 the opposite sign on 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 the output of the solution. {result="vector"} {result="table"}
