Inputs

y

Real matrix containing the output signal in time-domain. For a system with p outputs and n samples, y is a n-by-p matrix. For data from multiple experiments, y becomes a e-by-1 or 1-by-e cell vector of n(i)-by-p matrices, where e denotes the number of experiments and n(i) the individual number of samples for each experiment.

u

Real matrix containing the input signal in time-domain. For a system with m inputs and n samples, u is a n-by-m matrix. For data from multiple experiments, u becomes a e-by-1 or 1-by-e cell vector of n(i)-by-m matrices, where e denotes the number of experiments and n(i) the individual number of samples for each experiment. If u is not specified or an empty element [] is passed, dat becomes a time series dataset.

tsam

Sampling time. If not specified, default value -1 (unspecified) is taken. For multi-experiment data, tsam becomes a e-by-1 or 1-by-e cell vector containing individual sampling times for each experiment. If a scalar tsam is provided, then all experiments have the same sampling time.
