MATLAB: Bandpass Filter BPFILT-Does this function still exist

bandpassbpfiltfilterMATLAB

I have some code that uses bpfilt to apply a bandpass filter from 10 – 100 (presumably kHz):
flo=10;        
fhi=100;                                             
fdata=bpfilt(data,flo,fhi);
It looks like bpfilt doesn't exist as a function in matlab anymore? Is that true?
From reading other posts, it could also be that I am having trouble accessing the signal processing toolbox? I have this in my apps and it is enabled but I am not sure if that is enough to access the variables. I'm a newbie!
I would be happy to do the bpfilt by other means, but not sure how.
Thanks!!

I can’t find it in the online documentation. If you have R21018a or later, use the bandpass (link) function.
It’s easy to design an efficient elliptical filter with ellipord, ellip, zp2sos and filter it with filtfilt.
