clearInstrumentationResults

Clear results logged by instrumented, compiled C code function

Syntax

clearInstrumentationResults('mex_fcn') clearInstrumentationResults mex_fcn clearInstrumentationResults all

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.

Create a temporary directory, then import an example function from Fixed-Point Designer™.

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

Define prototype input arguments.

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

Generate an instrumented MEX function. Use the -o option to specify the MEX function name.
```
buildInstrumentedMex testfft -o testfft_instrumented -args {x,W}
```
Run a test bench to record instrumentation results. Call showInstrumentationResults to open a report. View the simulation minimum and maximum values and whole number status by pausing over a variable in the report.
```
for i=1:20
    y = testfft_instrumented(cast(2*rand(size(x))-1,'like',x));
end

showInstrumentationResults testfft_instrumented
```

Clear the results log.

clearInstrumentationResults testfft_instrumented

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

for i=1:20
   y = testfft_instrumented(cast(rand(size(x))-0.5,'like',x));
end

showInstrumentationResults testfft_instrumented

Clear the MEX function and delete temporary files.
```
clear testfft_instrumented;
tempdirObj.cleanUp;
```
