Why Create Multiexperiment Data Sets?
You can create iddata objects that contain several experiments. Identifying
models for an
iddata object with multip le e xp eri m e n ts results in an average
model.
In the S ystem Id entification Toolbox product, experiments can either
mean data collected during different sessions, or portions of the data
collected during a single session. In the latter situation, you can create a
