time

Extract time vector from simulation series

Syntax

tv = time(series)

Description

tv = time(series) returns a row vector of simulation times contained in the series. series is a simscape.logging.Series object. series must include a full identifier path to the series, starting with the workspace log variable name.

Examples

Extract Simulation Time Data for Spring Deformation

Return simulation time data for the deformation of a Translational Spring block.

Open the Mass-Spring-Damper with Controller example model:

openExample('simscape/MassSpringDamperWithControllerExample')

This example model has data logging enabled for the whole model, with the Workspace variable name parameter set to simlog_MassSpringDamperWithController.

Simulate the model for 1 second, to log the simulation data:

paramNameValStruct.StopTime = '1.0';
sim('MassSpringDamperWithController',paramNameValStruct);

Return the simulation time vector for the deformation variable of the Translational Spring block, Spring. x is the deformation variable name, and series is the Series object containing the simulation data for this variable.

t1 = time(simlog_MassSpringDamperWithController.Spring.x.series)

The t1 vector has 35 values, between 0 and 1, because the simulation series has 35 time steps and the simulation stop time is 1 second.

Input Arguments

series — Simulation series

Series object

Simulation series, specified as a simscape.logging.Series object. series must include a full identifier path to the series, starting with the workspace log variable name.

Output Arguments

tv — Times, in seconds, corresponding to time steps in simulation series

row vector

Times, in seconds, corresponding to the time steps in the simulation series, returned as a row vector.
