[Eeglablist] error with FIR

[shira frances]

hi,

i worked with eeglab on the trial matlab2017a for a month and every thing
was good. now i purchase a license, and i tried to work on the same data,
but i get an error messege when i try to filter the data.

*EEGLAB error in function pop_eegfiltnew() at line 218:*

*Undefined fuction 'freqz' for input arguments of type  'double'*

i  purchase in addition the Signal Processing Toolbox because i thought it
may help but it is the same.

it is the same data i used on the trial version, i dont understand what has
changed.

maybe i miss some kind of toolbox in matlab?


please help



thank you



shira
