normalizing plots for 1d vectors
Dear all, I have different 1d vectors to be plotted as curves into a single Figure. The y values across the vectors is not normalized. Therefore, I've some vectors with pretty small y-values (10^-8), and others ranging from [0-1]. The highest value of a given vector is always 1. Because of this, when I plot all ... 1 May 2010 13:10

Effect of temperature on Noise
I want to analyse the effects of temperature variations on SNR. SNR in dB = Pr - N Pr = Pt + G - L I have calculated Noise using the equation of N = k*T*B*F where k is boltzman's constant, B is the bandwidth, T is temperature and F is noise figure which is calculate by F = 1 + (T/290) When noise was calcul... 1 May 2010 13:10

fprintf column wise
Hi, I'm trying to print to a text file in one column so I can export this data into labview. But, I had trouble finding the syntax to do this. Here's the code I have. % Open a file for writing fid = fopen('test_002.txt', 'wt'); % print values in one column (now rows) fprintf(fid, '%f\c', data2); fclose(fid)... 1 May 2010 12:02

import 10GB data in Simulink
I'd like to import 10GB data from workspace for online simulation in Simulink. However, due to memory constraint, it's impossible. So how can I fix this problem? Can I read one part of the data first and then read the following part continously？ And how? ... 2 May 2010 05:31

Fastest way to create 4 GB files to disk?
Hi, I'm creating 4GB datasets and writing does to files on the HD. Basically, I need to read an original 4GB file, modify, write back to a NEW file. Does anyone have tips on optimizing such a process? Which techniques should I be looking at, etc. Any help is greatly appreciated, thanks. ... 1 May 2010 12:02

Client/Server Framework for Computing Clusters
Dear All: Just wanted to let you know I have developed a Client/Server Framework for Computing Clusters that you might find useful. Simple model with three commands (send file, receive file, spawn=fork/execute a program). There are three helper MEX files: spawn process (return pid), wait_pid (with timeout), and k... 3 May 2010 13:08

Ellipse & Fourier Descriptors
I'm working on an image processing problem where I'm analyzing the boundary of an object that I've segmented. I have the object's boundary sorted starting from the point closest to an angle of zero in the coordinate system and advancing to 2pi around the boundary. I then treat the boundary as a periodic signal (i.e... 1 May 2010 15:24

false color rendition images classification
I am working on Remote sensing satellite Image classification (supervised) using fuzzy logic . Include 2 steps 1. generate training data set for test images 2. Then use of fuzzy classification The result i obtained is satisfactory when test images of true color type ,but when i use FCR image then the classifica... 1 May 2010 23:05
