Class: fxpOptimizationOptions

Show tolerances specified for a system

Syntax

showTolerances(options)

Description

showTolerances(options) displays the absolute and relative tolerances specified for a system using the addTolerance method of the fxpOptimizationOptions class. If the options object has no tolerances specified, the showTolerances method does not display anything.

Input Arguments

fxpOptimizationOptions object specifying options and tolerances to use during the data type optimization process.

Open Script

Load the system for which you want to optimize the data types.

load_system('ex_auto_gain_controller');

Create a fxpOptimizationOptions object with default property values.

options = fxpOptimizationOptions;

To specify a required numeric tolerance to use during the optimization process, use the addTolerance method of the fxpOptimizationOptions object. To specify several tolerance constraints, call the method once per constraint. You can specify either relative, or absolute tolerance constraints.

addTolerance(options, 'ex_auto_gain_controller/output_signal', 1, 'AbsTol', 5e-2);
addTolerance(options, 'ex_auto_gain_controller/input_signal', 1, 'RelTol', 1e-2);

Use the showTolerances method to display all tolerance constraints added to a specified fxpOptimizationOptions object.
