In most cases, a model can be created by using a model estimation
command on a dataset. For example,
a continuous-time state-space model of order Nx using the input/output
of frequency response data DATA.
For ODEs (grey-box models), you must first construct the model
structure and then apply an estimation command (either
The following table summarizes System Identification Toolbox™ estimation commands. For detailed information about using each command, see the corresponding reference page.
