getSignalByIndex

Class: Simulink.sdi.Run
Package: Simulink.sdi

ReturnSimulink.sdi.Signal object by index

Syntax

signalObj = runObj.getSignalByIndex(index)

Description

signalObj = runObj.getSignalByIndex(index) returns the Simulink.sdi.Signal object, signalObj, at the index into the array of signals contained in the Simulink.sdi.Run object, runObj.

Input Arguments

expand all

Index to the array of signals contained in a Simulink.sdi.Run object, specified as an integer. The first index in the array is 1.

Output Arguments

expand all

Signal in a run object, Simulink.sdi.Run, returned as a Simulink.sdi.Signal object.

Examples

expand all

The Simulink.sdi.Run method, getSignalByIndex, returns a signal object representing the signal data and information in a run. You can modify the signal object properties to configure the signal for plotting or comparing to other signals in the Simulation Data Inspector.

% Configure model "slexAircraftExample" for logging and simulate
simOut = sim('slexAircraftExample','SaveOutput','on',...
					'SaveFormat','StructureWithTime',...
             'ReturnWorkspaceOutputs','on');
 
% Create a Simulation Data Inspector run
runID = Simulink.sdi.createRun('My Run','base',{'simOut'});
 
% Get the Simulink.sdi.Run object corresponding to the new run ID
runObj = Simulink.sdi.getRun(runID);
 
% Get the number of signals in the run
numSignals = runObj.signalCount;
 
% Get the Simulink.sdi.Signal object for the first signal in the run
if numSignals > 0
   signalObj = runObj.getSignalByIndex(1);
end

Introduced in R2012b
