This example shows how to load a set of logged data into memory all at once, rather than element by element.

% Simulate model to generate logged data
sim('sldemo_fuelsys')

The simulation logs all of the instrumented signals in the model to the Simulink.SimulationData.Dataset object sldemo_fuelsys_output. At the end of simulation, the signal data remains in the repository until used in the MATLAB workspace. When you work with small sets of data or only postprocess a subset, leaving signals in the repository improves performance. But when you have a large set of data and need to postprocess all of the signals, you should bring them all into memory at once.

% Load all logged signals into memory
loadIntoMemory(sldemo_fuelsys_output);

All of the data in sldemo_fuelsys_output is now available for efficient postprocessing.
