Reg, Your certainly right about the value of Donoho's introduction.? I can now think of Linear Programming as a method of dealing with problems where you have fewer equations than unknowns. Thanks

I use the simplex solver in GLPK, the Gnu Linear Programming Kit with arbitrary precision arithmetic. I cannot recommend it more highly. Linear algebra is the means. The difference just is the problem

Thanks Reg, Perhaps the link you furnished will provide more insight.? I always felt there was a big gap between linear algebra,? and the linear programming used in business applications.? Because

Yes, I am talking about linear programming as developed by Dantzig in the late 40's for solving logistical problems for USAF. Lots of linear algebra, but quite a lot more. It is Traveling Salesman and

Reg, I apologize for this being off topic.? I am afraid I cannot be of any help with the design of crystal filters as my only experience with them has been to use a resistance-loaded 100 MHz crystal

There is quite a lot of literature and software for designing filters using idealized xtals, but so far as I can find, no one has presented selecting which N xtals from a set of P xtals will best

Yes, I will.

Might I suggest you try it again. They do move URLs around a bit. Try https://sci-hub.se/ If not you might have to use a proxy server. But of the statistics I have seen, more papers are downloaded

At your suggestion I tried sci-hub awhile back and found that it does not work in the US. DaveD

LoL! I was an ACM member for a good while, but eventually realized I *never* used the digital library I was paying them for. And the "Transactions" were such an exercise in buzzword bingo as to be

Definitely, only reason I'm a member at all is because work pays the dues and it looks good on your CV. And we have full institutional access. Otherwise, I wouldn't bother. I dropped ACM a long time

I'll look into that this weekend. Sean

Yes, I agree. And I feel as if, having been an IEEE member for many decades, I should be afforded some sort of exception to the normal rules. While I was forcebly retired, I am still a practitioning

My working practice as a research programmer was to pull from 20-50 papers in preparation. At the IEEE *member* rate for papers that would make it uneconomic without institutional access. Fortunately

Sean, Would you post scans of those 4 pages in the Files section in a "Yagi-Uda" directory? There's a FORTRAN code by Morris. I'm still looking for his dissertation.

Indeed. I would say that it stops being reasonable at all for very old work, such as the reference above. A journal from 1966 cannot be a source of revenue now; they ought to have a cut off age where

No, sharing documents from IEEE, ARRL and other organizations has always been verboten unless the document in question is specifically not copyrighted. And that is not unreasonable, even if it is

Bummer! And FYI for others, IEEE is watermarking stuff you download from them now. So take care if you plan to share, that it doesn't blow up in your face later. For that reason, I am not able to

Cool. Unfortunately I no longer have access to the IEEE digital library.
