convert an array to time series and input to simulink

HI all

A matlab simulink file is runing, an input is given to the m file, processes are done inside the m file, an array (double) with a row of time and a row of digital data is created.

each time cell indicates for how many second the corresponding digital data is valid.

for instance:

 time  Digital data

1 0

4 1

2 1

3 0

I need to turn this array back to my simulink and use it. the problem is that I need it as time series. each calculated value should be send out consecutively for the use of other parts of simulink file.

any idea?

I have checked time series help, but could not address the problem.

tnx

Hey @Mohammad Ali Khademi, I assuume that you want to convert your array of time and digital data into a time series format suitable for Simulink, for that you can use MATLAB's timeseries object as per the below given way:

1. Prepare the Data: Ensure your array contains two rows, with the first row representing time intervals and the second row representing digital data values.
2. Accumulate Time: Convert the time intervals into cumulative time points.
3. Create a Time Series: Use the timeseries function to create a time series object.
4. Use in Simulink: Pass the timeseries object to Simulink using a From Workspace block.

Below I have attached the sample code:

% Example data
timeIntervals = [1, 4, 2, 3]; % Time intervals
digitalData = [0, 1, 1, 0];   % Digital data values

% Calculate cumulative time points
cumulativeTime = cumsum(timeIntervals);

% Create a timeseries object
ts = timeseries(digitalData, cumulativeTime);

% Display the timeseries
disp(ts);
