To provide a sequence of vectors as input to the LSTM 'Stateful Predict' block in Simulink, you can accumulate the vectors over time within a MATLAB Function block and transform it to a “timeseries”.
Here’s how you can implement this:
Add a MATLAB Function block to your Simulink model to store and update a buffer that accumulates vectors from consecutive timesteps. You can now use this output as input to your “Stateful Predict” block.
function timeseriesData = inputToTimeSeries(u)
% u: Current input vector from the Mux block
% Define persistent variables for the buffer vector
persistent buffer;
buffer = [buffer ;u];
% Convert the buffer to a timetable
timeseriesData = array2timetable(buffer, 'TimeStep', seconds(0.2));
end
