Hello,
When I run the "signal/BandpassFilteringOfTonesExample" I get an error that reads:
"Error using bandpass
Not enough input arguments."
Thank you,
Carolina

I get the following:
/Downloads/amtoolbox-full-0/code/thirdparty/sfs/SFS_general/bandpass.m
/Applications/MATLAB_R2021a.app/toolbox/signal/signal/bandpass.m % Shadowed
It seems like it is getting shadowed by another function. How can I point to the one from the signal processing toolbox?
Thank you

You appear to have installed Auditory Monitoring Toolbox from https://sourceforge.net/projects/amtoolbox/files/
You will need to move the directory /Downloads/amtoolbox-full-0 to the end of your MATLAB path (use pathtool for that)
Or else go into the code and rename /Downloads/amtoolbox-full-0/code/thirdparty/sfs/SFS_general/bandpass.m to /Downloads/amtoolbox-full-0/code/thirdparty/sfs/SFS_general/sfsbandpass.m and edit all the code under /Downloads/amtoolbox-full-0/code/thirdparty/sfs that refers to bandpath to instead refer to sfsbandpass . Which is a nuisance. But even if you do move the toolbox to the end of your MATLAB path, when you go to use the toolbox, unless you did the rename, it would probably end up using the MATLAB bandpass instead of its own.
In some cases, if the only calls to bandpass in the toolbox are from files in the SFS_general directory, then instead of doing the renaming, you could create a subdirectory named private in the directory and move /Downloads/amtoolbox-full-0/code/thirdparty/sfs/SFS_general/bandpass.m to /Downloads/amtoolbox-full-0/code/thirdparty/sfs/SFS_general/private/bandpass.m

Thanks very much for your help! I ended up renaming the bandpass function from the AMT toolbox since the AMT scripts I’m using don’t ever call that function.
