Filter designer fails

[rgetz]

When setting all the half bands to decimate/interpolate by 1,

the design function fails with:

AD9361_Filter_Wizard Undefined function 'cascade' for input arguments of type 'double'.

Error in internal_design_filter (line 265) dfilter = cascade(filter_stages{:});

Error in AD9361_Filter_Wizard>create_filter (line 1107) filter_result = internal_design_filter(filter_input);

and the GUI hangs.

I don't know if this still happens?

You get a warning from the designer that a filter cannot be designed for this configuration. Code change came here: https://github.com/analogdevicesinc/ad936x-filter-wizard/commit/93aa9f0fd1a2620331f88919b3df85b0f77740bb

Thanks for checking.
