Enable Plotting Using the Simulation Data Inspector

You can use the Simulation Data Inspector (Simulink) to inspect and compare floating-point and fixed-point input and output data logged using the codegen function. At the MATLAB^® command line:

Create a fixed-point configuration object and configure the test file name.
```
fixptcfg = coder.config('fixpt');
fixptcfg.TestBenchName = 'dti_test';
```
Select to run the test file to verify the generated fixed-point MATLAB code. Log inputs and outputs for comparison plotting and select to use the Simulation Data Inspector to plot the results.
```
fixptcfg.TestNumerics = true;
fixptcfg.LogIOForComparisonPlotting = true;
fixptcfg.PlotWithSimulationDataInspector = true;
```

Generate fixed-point MATLAB code using codegen.

codegen -float2fixed fixptcfg -config cfg dti
