Canon command and state names
Given a state space system sys, calculated from the linearization of a Simulink model, I simply calculate its modal representation with csys=canon(sys,'modal'). I don't understand why the state names in csys are preserved instead of being reset. This is misleading, since the state vector components order of csys is giv... 25 Jun 2010 07:42

Basic question about FFT and PSD
Dear everyone, I am sorry to bring such a basic question. I hope you don't mind to answer my questions below: 1. I have calculated the FFT for a sample signal and I got a spectrum with x-axis represented frequency and y-axis represented by amplitude. And the result is correct,, the amplitude and the frequency are... 25 Jun 2010 18:40

LDA ouput as classes seperated well in plot
i dont know much about lda but i want to learn. for the time being i want to see the result how it can distinguish classes , on plot. i want to see two seperate clusters on the plot. i know that lda transformation will do good seperability. i know the within class matrix and between class ma... 25 Jun 2010 07:42

Equations of Motion
Hi everyone, I am trying to build a model of a car accelerating from standstill over a 0.5 seconds time duration in millisecond intervals. For now I am only concerned with the angular displacement, angular velocity and angular acceleration of the body. I have a working model in Excel and am now trying to do the sa... 25 Jun 2010 07:42

problem with plotting differential equation
I have got following code: y=dsolve('Dy=y*(1-y/5)','y(0)=6','x'); solution=inline(vectorize(y),'x'); x=0:0.01:10; plot(x,solution(x)); It is the logistic equation which is plotted well. However If I change the code to: y=dsolve('Dy=y*(1-y/5)+sin(x)','y(0)=6','x'); solution=inline(vectorize(y),'x'); x=0:0.... 25 Jun 2010 09:52

Using light on specific object
Hi, Is there any way in MATLAB 7.0 (R14) to apply light to a specific object only? At first I thought this can be performed by setting the 'Parent' property of the light to a hggroup. However, actually MATLAB 7.0 can't do this; there is a documentation error: http://www.mathworks.nl/support/solutions/en/data/1-13I0... 25 Jun 2010 05:32

linear approximation for cubic curve
Hello I want to approximate cubic curve with straight segments with given tolerance. The point is that I want to have fewer segments where curve is mostly flat and more segments where curve bends. Is there any function in matlab that can do this? Thanks, Didi ... 25 Jun 2010 08:47

Background elimination
Can you tell me how to eliminate the background, whatever it may be, from an image containing written text? I have to remove the background from an image containing a signature&#8230; The problem is the intensity of the signature and that of a line in the background is almost the same&#8230; please help.. thanks&#8... 30 Jun 2010 07:34
