Select the data format for saving states, output, and final states data.
Category: Data Import/Export
Logged states and outputs are each stored in a
Simulink.SimulationData.Dataset object. Each
Dataset object contains an element for each
individual state or output. The data for each state or output is stored
timeseries object by
default except variable-size signal data. Variable-size signal data is
always stored in a
timetable object that contains a
cell array of signal values for each time step.
Logged data is stored in a matrix. Each row in the matrix corresponds
to a simulation time step, and each column corresponds to a state or
output. The order of the states and outputs in the matrix depends on the
block sorted order, which can change from one simulation to the next. Do
Array format to log bus data.
State and output data each log to a structure. The states structure contains a structure for each block in the model that has a state. The outputs structure contains a structure for each root-level Outport block in the model.
Structure with time
The data logs to a structure with a time field and a signals field.
The time field contains a vector of simulation times. The signals field
contains the same data as the
When you log states and output data using
You can work with logged data in MATLAB® without a Simulink® license.
Logging supports saving multiple data values for a given time step, which can be required for logging data in a For Iterator Subsystem, a While Iterator Subsystem, and Stateflow®.
Logged data automatically streams to the Simulation Data Inspector during simulation.
You can log variable-size signals using root-level Outport blocks.

Use another format if the outputs and states in your model do not meet these conditions.
The format specified for the Format parameter does not apply to final states data.
