Root Finding Model
Location in Objects Pane
- Models > Model > Generic > Root Finding
- This model finds the root of a general nonlinear single-variable equation
- Name of the object in Rt
- Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
- The name is unique and case-sensitive.
- Determines whether the model is allowed to print messages to the Output Pane.
- Expression of the equation, for example:
x^2 – sin(x)
- In the expression, “x” is the unknown variable
- Algorithm of the solver that can be one of the following:
Newton, Secant, Steffenson, Bisection, False Position, and Brent Dekker
- Maximum number of iterations
- Acceptable error in finding the root
- Starting point of searching for root, used in derivative-based algorithms, namely Newton, Secant, and Steffenson.
- Lower bound of the searching interval, used in bracketing algorithms, namely Bisection, False Position, and Brent Dekker.
- Upper bound of the searching interval, used in bracketing algorithms, namely Bisection, False Position, and Brent Dekker.
- The root of the equation
- The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
