You can use the MATLAB® plotting functions for visualization of your non-real-time simulated data or your real-time executed data.
After running your real-time application and logging data to a file, you can plot the data.
This procedure uses the model
sldrtex_model. To open this model, in
the MATLAB Command Window, type:
It assumes that you saved your data to the variable
The steps in this procedure assume that you have already loaded that model and have completed the steps in Set Scope Parameters for Logging to File, Set Run in Kernel Mode Properties for Logging to File, and Set Run in Kernel Mode Data Archiving Parameters.
In the Simulink® Editor, on the Desktop Real-Time tab, click Run in Real Time.
When the real-time application runs, it creates the
ScopeData variable that you configured in Set Run in Kernel Mode Properties for Logging to File and creates the archive data files that you
configured in Set Run in Kernel Mode Data Archiving Parameters.
In the MATLAB Command Window, type:
ScopeData = time: [10000x1 double] signals: [1x1 struct] blockName: 'sldrtex_model/Scope'
To list the MAT-files saved to your disk, type:
To clear the MATLAB workspace and load the scope data, type:
clear load data_0 who
Your variables are: ScopeData
To plot the first 1000 points, type:
plot(ScopeData_0.time(1:1000), ... ScopeData_0.signals.values(1:1000))
The MATLAB environment plots the first
1000 samples over
