Saving and Opening Filter Design Sessions

You can save your filter design session as a MAT-file and return to the same session another time.

Select the Save session button to save your session as a MAT-file. The first time you save a session, a Save Filter Design File browser opens, prompting you for a session name.

For example, save this design session as TestFilter.fda in your current working directory by typing TestFilter in the File name field.

The .fda extension is added automatically to all filter design sessions you save.

Note    You can also use the Save session and Save session as menu items in the File menu to save a session. This dialog opens every time you select the Save As menu item.

You can load existing sessions into the Filter Design and Analysis Tool by selecting the Open session button, or Open Session from the File menu. A Load Filter Design File browser opens that allows you to select from your previously saved filter design sessions.
