System Identification Toolbox

Workspace Variables

The models and data sets created within the GUI are normally not available in the MATLAB workspace. Indeed, the workspace is not at all littered with variables during the sessions with the GUI. The variables can however be exported at any time to the workspace, by dragging and dropping the object icon on the To Workspace box. They will then carry the name in the workspace that marked the object icon at the time of export. You can work with the variables in the workspace, using any MATLAB commands, and then perhaps import modified versions back into the GUI. Note that models and data are exported as the toolbox's objects idmodel, idfrd, and iddata. For how to extract information and work with these objects, see Tutorial and Model Conversions of the "Command Reference "chapter.

The GUI's names of data sets and models are suggested by default procedures. Normally, you can enter any other name of your choice at the time of creation of the variable. Names can be changed (after double-clicking on the icon) at any time. Unlike the workspace situation, two GUI objects can carry the same name (i.e., the same string in their icons).
