? smallest eigenvalue
Hi: eigs() gives the eigenvalues of the largest magnitudes, but what is the command that gives the eigenvalues of the smallest magnitude? Also what is the command that gives largest/smallest eigenvalue ( not in magnitude but take the sign into account)?

find smallest integer such that...
Guys, thanks a lot for all your answers concerning my last question. I am still learning a great deal about Mathematica. Here's a second puzzle. Given an expression e(k,w) 10^i(-k - w) find the smallest w such that the term is smaller than a predescribed bound b. For growing w the term is decreasing and converging towards 0. Your help is very appreciated. Best, Thomas

selecting smallest rec
I am trying to select a record based on the smallest value of a variable. proc sql errorstop; create table goodscr as select * from champion2 having min(col1); quit; The data looks like name col1 green 37 blue 125 brown 325 I want to keep only the record with the smallest value from col1. The sql is ignoring my having clause. Nope, it's not ignoring your having clause. Correct your having clause as follows: having col1=min(col1) Your present having clause always evaluates as true because min(col1) is non-zero, non-missing. s/KAM "Nicole Bibb" <nicole.d.bibb@WELLSFARGO.COM> wrote in message news:200407080023.i680NH828791@listserv.cc.uga.edu... > I am trying to select a record based on the smallest value of a variable. > > > proc sql errorstop; > create table goodscr as > select * > from champion2 > having min(col1); > quit; > > The data looks like > > name col1 > green 37 > blue 125 > brown 325 > > I want to keep only the record with the smallest value from col1. > > The sql is ignoring my having clause.

biggest or smallest numbers in gfortran
Hi all, is there a program and/or table that gives me the biggest number (just before overflow) and the smallest number (just before underflow) for "REAL*4, REAL*8 - may be REAL*16 -, INTEGER*2, INTEGER*4 or INTEGER*8 in gfortran under a Linux x64 architecture? I use gfortran v4.5. Is there somewhere a description, how these numbers are stored internally? I remember such things from former times (IBM 370, etc. - please don't laugh!) Thanks in advance, Uwe.

Better. There are standard-defined intrinsics. Look up HUGE etc. >Is there somewhere a description, how these numbers >are stored internally?

An Ultra 5 is about the size of a desktop version of "PC vulgaris". An Ultra 10 is about the size of a PC "micro tower". Either machine is generally available on e-Bay for less than $100 US. If you want something a little faster and a little more recent look for a "Blade 100" or a "

Smallest real positive root
Is there a quick way in matlab to give me the smallest possible real root of something I am casting a ray with. Newtons, seecannt are too slow.

Newtons, seecannt are too slow. Sorry, but um, no. John I want to cast a ray and find the smallest root where it intersects a surface. you can easily do this with Newtonns method or Seecant but takes forever to converge and you need a good intervals.

Searching for the smallest readable font.
!!!): http://www.underware.nl/site2/index.php3?id1=unibody&id2=family I've never done it, but to rasterize vector fonts, try: http://www.fontlab.com/html/fonmaker.html The demo may let you do what you need. If not, try Softy... Google for "pixel fonts". I would take a narrow one as for example WYSP REGULAR: http://www.wpdfd.com/pixelfonts.htm The smallest one at all is perhaps SCRIPTO NARROW: http://www.minifonts.com/scripto.html You can convert them to Bitmap with, for exampl. FONTMAKER. Greet. And although the fonts Klaus suggests are not "free", I think $8-15

Smallest uClinux configuration
I am trying to get uClinux to run in under 2MB of RAM without flash and if possible to still have networking support. All I need is basic command line support and the ability to load and execute one additional program. I'd guess that a bunch of people have tried this before and would appreicate any help/suggestions on how best to setup the uClinux build configuration. Thanks, Justin Hi Justin, Justin Erickson wrote: > I am trying to get uClinux to run in under 2MB of RAM without flash and if > possible to still have networking support.

Smallest PC bluetooth card?
Hello, I am looking to add Bluetooth to my laptop and would like suggestions. I want to be able to keep the Bluetooth card in the laptop at all times without it protruding from the side. I found one, Socket Compact Flash card with PC Card adapter, that looks promising. See link below. Anyone have any sucess with the Socket CF w/ PC Card adapter? Are there any others brands out there that are flush to the side of a laptop? By the way I have an Acer TM800 laptop. thanks!
