[Eeglablist] pop_eegfiltnew() error

[Mikołaj Magnuski]

Hi,

freqz is probably a variable  used in the filtering function but you seem
to have a script freqz.m somewhere on your path.

The more general problem is that in matlab, unlike many other programming
languages (R, Python, Julia etc.) the indexing operation uses the same type
of parentheses as function call. (another problem is no namespaces) Because
of this you may sometimes run into errors like the one you are reporting.
To be sure whether it is this kind of error - please paste the whole error
information (including the information about the stack of calls).
