i found that for FIR filters, both firpm() (used to be called remez())
and firls() work pretty good for design. and also the Kaiser window
(together with fft()) works pretty good for the "windowing method" of
they should have a berchin() function along with prony() to design IIRs
in the signal processing toolbox.
i wonder what Ingle and Proakis would say about the STUPID FUCKING
requirement that all indices are positive (not ever zero, not ever
negative). how do they integrate that inflexible indexing convention
into the accepted and concise convention we use in DSP that has negative
and zero indices, both for samples and for FFT bins? and about the
latter, *what* do they tell the reader about the DC bin in the FFT? is
it X(1)? totally stupid, and you would think these authors would start
rattling Cleve's telephone and tell him how that unfixable indexing
convention makes it harder to integrate MATLAB with their DSP book.

No tags are associated with this thread.
A tag is like a keyword or category label associated with each thread. Tags make it easier for you to find threads of interest.
Anyone can tag a thread. Tags are public and visible to everyone.
The newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.
Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.
Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.
There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.
You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.
Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.
Your MATLAB Central account is tied to your MathWorks Account for easy access.

The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.
Most newsgroup spam is filtered out by the MATLAB Central Newsreader.
Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.
