target.ProfilingFreezingOverhead Class

Namespace: target

Capture freezing and unfreezing instrumentation overhead

Since R2021a

Description

Use a target.ProfilingFreezingOverhead object to capture the instrumentation overhead for freezing and unfreezing a timer.

To create a target.ProfilingFreezingOverhead object, use the target.create function.

Examples

Specify Function Instrumentation Overhead

Manually specify the function instrumentation overhead for a timer.

Retrieve the target.Processor and target.Timer objects.

processor = target.get('Processor', 'myProcessorObjectId');
timer = target.get('Timer', 'myTimerObjectId');

Create a target.ProfilingFreezingOverhead object.

freezingOverhead = target.create('ProfilingFreezingOverhead', ...
                                 'Name', 'Timer Freezing Overhead');
freezingOverhead.Value = 30;
freezingOverhead.Counter = timer;
