    This is a bug in Release 13 that occurs only when the Signal Processing Toolbox has been upgraded to R13+ but the Filter Design Toolbox has not. To fix the issue, install both the Signal Processing Toolbox 6.1 (R13+) AND Filter Design Toolbox 2.5 (R13+).
    NOTE: As explained in the Release Notes for both the Signal Processing Toolbox 6.1 and the Filter Design Toolbox 2.5, you must first UNINSTALL the existing toolboxes before installing the new upgrades.
