Why am I unable to start FDATool in the Signal Processing Toolbox 6.1 (R13+) when the DSP Blockset and/or Filter Design Toolbox license has expired? I receive the following errors when I try to start FDATOOL after the DSP Blockset license has expired. However, the FDATOOL is part of the Signal Processing Toolbox and should be independent of the DSP Blockset license. ??? Error using ==> feval Undefined function 'fdplugin'. Error in ==> C:\Matlab6p5\toolbox\signal\sigtools\addplugins.m On line 44 ==> fcnStruct = feval(pluginStruct.plugin{j}); Error in ==> C:\Matlab6p5\toolbox\signal\sigtools\private\fdatool_sidebar.m On line 27 ==> addplugins(hSB); Error in ==> C:\Matlab6p5\toolbox\signal\sigtools\private\addcomponents.m On line 9 ==> fdatool_sidebar(hFDA); Error in ==> C:\Matlab6p5\toolbox\signal\sigtools\fdatool.m On line 32 ==> addcomponents(hFDA);

A bug affecting Signal Processing Toolbox 6.1 (R13+) has been fixed in Release 14 (R14) with version 6.2. The bug involves FDATOOL handling license information from DSP Blockset and Filter Design Toolbox. If you are using a previous release, the workaround is to uninstall any DSP Blockset and/or Filter Design Toolbox that have expired licenses.
