WindowScrollWheelFcn and ginput problem
Hi Petros, I'm running into the same problem with GUI, WindowScrollWheelFcn, and ginput. Were you able to ever correct this and if so how? Thank you for your time, Jon "Petros" <painter(a)geo.auth.gr> wrote in message <gv6ld8$q6h$1(a)fred.mathworks.com>... well, here it goes. I am building a gui and I... 6 Oct 2009 03:12

question on using fft2 to calculate diffraction pattern
Hi guys, I could compute the diffraction pattern of a small slit where the slit was in the order of several 10s of microns, using FFT2. I then tried to compute the diffraction spot (PSF) of an aberrated imaging system by propagating the aberrated wavefront from the exit pupil to the image plane. I'm not sure ho... 5 Oct 2009 03:35

Dual axis plots
i am trying to plot two data sets in one graph with different y axis as both the data sets have different length. I am able to plot two data sets . Is there a way to plot a 3rd data set on the same graph? if i am using a same x axis scale. i am using [haxes,hline1,hline2] = plotyy(plottimev, T22AvgPower,plottimesc... 4 Oct 2009 19:57

How to get discretize K matrix given by n4sid tool
Dear Sirs, please I would want to know if somebody have an idea about how to do the following: I've got a model of my system using the n4sid tool; I set it in order to get a continuous time model; ze is my iddata model with experimental input and two outputs mc = n4sid(ze,order,'Ts',0,'ssp','can','ini','z') So... 4 Oct 2009 14:21

polyfitn , polyn2sym
Hi everyone, I am using these two functions and trying to generate the symbolic expression i.e. the output of the function: polyn2sym like the following. 5*X1.^2+8*X1.*X2+6*X1.*X3-7*X1+4*X2.^2+4*X2.*X3-6*X2+2*X3.^2-7*X3+7 I want to have the expression like above: want a array products ".*" not matrix product "*"... 4 Oct 2009 14:21

Park's Transformation for PMSM
Does Park's Transformation (dqo transformation) vary with the number of poles for a permanent magnet synchronous motor? If it does change with the number of poles does anyone have the generic pole dependent derivation? I have seen some diagrams in several books that show the d and q axis NOT perpendicular to each ot... 5 Oct 2009 09:02

problem with exporting figure to .eps
Hi, I'm trying to export a figure which has subplots to an eps file, using exportfig.m. For some reason, I only see the first out of the 4 subplots on the figure. In addition, my editor (I'm using LyX) is having problems with viewing the figure. It seems like the fact it contains subplots is what makes problems, be... 5 Nov 2009 09:59

outliers from robustfit
I am using robustfit(x, y) to do linear regression. I wonder whether, how can I get the information, which datapoints where considered during the fit as outliers, i.e. if I plot the data and the regression line, I see that x5,y5 are way out. But how can I get this automatically? Thanks ... 5 Oct 2009 11:15

Integration of Simulink Model Compare in SVN
Dear all, I just tried the tool now finally provided by MW in the Simulink Report Generator toolbox to compare Simulink models (visdiff('model1','model2'). Since we use Tortoise SVN for source control I would be very interested how to integrate this tool into Tortoise SVN. In Settings/External Programs/Diff V... 4 Oct 2009 05:35
