Transformer equivalent circuit
Can someone help me to find some e-document in which parameters of typical distribution transformers are given including saturation and hysteresis data? By "typical transformers" I mean those standard transformers , like : Rated primary voltage : 34,5kV Rated secondary voltage : 0,4kV - 0,69 kV Line & Freq... 21 Jan 2010 18:02

MCR preload
Is it possible to preload the MatLab Compiler runtime engine (MCR) prior to starting an application? Currently it can take 45 to 90 seconds depending on the computer to start an application by calling (or double clicking) on the compiled .exe file. I assume most of that time is required to load the MCR. We are deployin... 21 Jan 2010 18:02

IIR filter coefficients
I have a question regarding the design of IIR bandpass filter. From the desired filter shape, Ws1 = 0.4, Wp1 = 0.45, Wp2 = 0.55 ,Ws2 = 0.6, Rp = 0.5, Rs = 50. I'd like to know the coefficients of the numerator and denominator of transfer function in descending powers of z. It seems like that order N=4, but why the coe... 22 Jan 2010 00:44

How to transfer variables from LabVIEW to Matlab?
Dear NG, I've got a legacy test stand that is running LabVIEW. Now I would like to do some analysis and post processing using Matlab. What is the best way to transfer live variable values from LabVIEW to Matlab? * Via TCP or UDP? Seems to be cumbersome and error prone. * An OPC server? When I see it right, M... 28 Jan 2010 00:59

angle from rotation matrix
Roger's message (below) mentions "It can be shown, 1) that the trace of A must equal 1+2*cos(theta) where theta is the counterclockwise angle of rotation, ...". I'm hoping that smeone can share how to show this with either linear albegra, Lie Theory or both. Thanks, John. "Roger Stafford" <ellieandrogerxyzzy(a)mindsp... 15 Feb 2010 02:10

bootstrp and bootci don't work if data inputs are not same length
just incase anyone thought the documentation could have poss been a tiny bit better for matlabs bootstrapping: x = normrnd(10,2,100,1); ci = bootci(1000,@nanmean,x); %my conf limits (95%) [bootstat,bootsam] = bootstrp(1000,@nanmean,x); mymean = mean(bootstat); also of interest: http://www.csp.curtin.edu.au... 21 Jan 2010 13:26

Double integration on infinite rectangles
Hi all, is there any way to calculate a double integral on an infinite rectangle? As an example, I would like to calculate something like integrand = @(x,y)exp(-x.*y); quad2d(integrand,0,Inf,1,2) whose solution is log(2), but quad2d only accepts finite arguments and I have to use an approximation like ... 21 Jan 2010 13:26
