The Metrics Dashboard user interface, metricdashboard function, slmetric package API, and corresponding customizations will be removed in a future release. For more information, see Migrating from Metrics Dashboard to Model Maintainability Dashboard.

Syntax

stats = getStatistics(metric_engine,MetricID)

Description

Generate statistics on the Value properties of the slmetric.metric.Result objects for the specified metric engine object, metric_engine.

stats = getStatistics(metric_engine,MetricID) generate statistics for the specified metric identifier.

example

Input Arguments

expand all

When you call execute, metric_engine collects metric data for all available metrics or for the specified MetricID. Calling getMetrics accesses the collected metric data in metric_engine.

Metric identifier for Model Metrics or custom model metrics that you create. You can get metric identifiers by calling slmetric.metric.getAvailableMetrics.

Example: 'mathworks.metrics.DescriptiveBlockNames'

Output Arguments

The Statistics object contains the following properties:

  • MinValue is a double that returns the minimum of the Value of the slmetric.metric.Result object.

  • MaxValue is a double that returns the maximum of the Value of the slmetric.metric.Result object.

  • MeanValue is a double that returns the mean of the Value of the slmetric.metric.Result object.

  • StandardDeviation is a double that returns the standard deviation of the Value of the slmetric.metric.Result object.

Examples

This example shows how to create a slmetric.Engine object, set the analysis root, collect the block count metric, and collect statistics for the model sldemo_fuelsys.

% Open the example model
openExample('sldemo_fuelsys')

% Create an slmetric.Engine object
metric_engine = slmetric.Engine();

% Specify model for metric analysis
setAnalysisRoot(metric_engine, 'Root','sldemo_fuelsys');

% Generate and collect model metrics
metricID = 'mathworks.metrics.SimulinkBlockCount';
execute(metric_engine, metricID);
stats = getStatistics(metric_engine, metricID);
