Simulation Time
Hi, I am bit confused on the simulation times in simulink bar. What are the units of that? Lets say i put start time 0 and the stop time 24. What would be that 24? Is it secs minutes days or what? How can i specify that. As i want to run the simulation and have results for 24 days. So should i just put 24 or there i... 16 Apr 2010 04:00

fsolve
I want to make out x,my procedure is as follows: function f=yt(x); f=[exp(-x(1)*6.1)*x(6)+x(7)*exp(-x(2)*6.1)+(1-x(6)-x(7))*exp(-x(3)*6.1)-(1-0.6944);exp(-x(1)*28.15)*x(8)+x(9)*exp(-x(2)*28.15)+(1-x(8)-x(9))*exp(-x(3)*28.15)-(1-0.8992);exp(-x(1)*30.43)*x(10)+x(11)*exp(-x(2)*30.43)+(1-x(10)-x(11))*exp(-x(3)*30.43)-(1-... 16 Apr 2010 10:33

Hi, I'm doing a project in Cognitive radio and I need to do some simulation with matlab. If any one have done previous simulation or have got some Please can he help and send me a copy (M-file) to help me in my simulation. ... 16 Apr 2010 01:51

Newbie to Hibert Transform
Hi all, I am new to Hilbert transform. I found its definition from text book h(f) = -j or -90degree, f>0 h(f) = j or 90degree, f<0 h(f) = 0, f=0 But when I plot the phase out, code as follow. The phase changes with frequency and is not fixed at -90 or 90 degree. What do I miss? b = firpm(10,[.1 .9],[1 1],'... 16 Apr 2010 17:19

Minimax problem for matrices
Hi there I'm facing a problem for which I haven't yet found an answer. Hopefully gathering all the expertise of the forum I'll be able to move forward! The problem is as follows, I have two matrix that respectively represent two functions. Actually they are hipermatrix since they have three dimensions. What I wan... 16 Apr 2010 00:45

Real-Time Windows Target and RS232 communication?
Hi guys, I know that recent versions of Real-Time Windows Target (RTWT) support the RS232 communication better than previous versions. But I need to know more about how well RTWT can support RS232. For example, I have some questions as follow: 1. If I have a RS232 port which is set to run at baudrate 115200 (or e... 16 Apr 2010 00:45

robot webcam image processing
hi, so i've made a gui that will be used for real time control of a robot. part of it includes reading from the robots webcam. the code i used is: vid=videoinput('winvideo',1); vidRes = get(vid, 'VideoResolution'); nBands = get(vid, 'NumberOfBands'); hImage = image( zeros(vidRes(2), vidRes(1), ... 26 May 2010 09:08

acceleration to displacement accelerometer data
Hi all, I have a problem which seems simple enough, but I just can't work it out. I have discrete accelerometer data from an IMU, which is collecting data at 10Hz. I have 6DOF being the x, y, z linear accelerations, and the roll, pitch, yaw rate. I want to convert the linear accelerations to displacements and th... 16 Apr 2010 05:05

Distribution
Hello, For a particular word, I calculated a 12 dimensional MFCC. I want to know what sort of distribution exists in these feature vectors, whether the distribution is normal, gaussian, or rectangular. But I am not sure how to go about calculating (plotting) the distribution of the MFCC features. Could someo... 16 Apr 2010 00:45

Help request: Image segmentation loop
Hi, I am new to medical imaging analysis and matlab. Here is what I am trying to solve, hope you can provide me some guidance: I am trying to segment an image into smaller blocks and analyze data those blocks individually. For example, I have a 20x20 image (grayscale) and I want to segment into four blocks and form a... 16 Apr 2010 21:46
