clearInstrumentationResults - Clear results logged by instrumented MEX function

Syntax

Description

clearInstrumentationResults('mex_fcn') clears the results logged from calling the instrumented MEX function mex_fcn.

clearInstrumentationResults mex_fcn is alternative syntax for clearing the log.

clearInstrumentationResults all clears the results from all instrumented MEX functions.

Input Arguments

mex_fcn

Instrumented MEX function created using buildInstrumentedMex.

Examples

Run a test bench to log instrumentation, then use clearInstrumentationResults to clear the log.

1. Create a temporary directory, then import a demo function from Fixed-Point Toolbox.

   tempdirObj=fidemo.fiTempdir('showInstrumentationResults')
   copyfile(fullfile(matlabroot,'toolbox','fixedpoint',...
      'fidemos','fi_m_radix2fft_withscaling.m'),...
      'testfft.m','f')

2. Define prototype input arguments.

   n = 128;
   x = fi(zeros(n,1);
   W = coder.Constant(fi(fidemo.fi_radix2twiddles(n));

3. Generate an instrumented MEX function. Use the -o option to specify the MEX function name.

   buildInstrumentedMex testfft -o testfft_instrumented -args {x,W}

4. Run a test bench to record instrumentation results. Call showInstrumentationResults to open the Code Generation Report. View the simulation minimum and maximum values and whole number status by hovering over a variable in the report.

   for i=1:20
       y = testfft_instrumented(randn(size(x)));
   end
   
   showInstrumentationResults testfft_instrumented

5. Clear the results log.

   clearInstrumentationResults testfft_instrumented

6. Run a different test bench, then view the new instrumentation results.

   for i=1:20
      y = testfft_instrumented(randn(size(x)));
   end
   
   showInstrumentationResults testfft_instrumented

   

7. Clear the MEX function and delete temporary files.

   clear testfft_instrumented;
   tempdirObj.cleanUp;
