adding elements to a matrix
Hi everybody, I want to create a matrix where some elements is added to the former one while iterating by j. (a+((j-1)/j)) assume a=1:1:10 for j=1:2 b=sort([b(1:j-1,:) a+[(j-1)/j]]) end where I get: b=[1.0000 1.5000 2.0000 2.5000 3.0000 3.5000 4.0000 4.5000 5.0000 5.5000 6.000... 13 May 2010 13:48

Text File With Header
Hi, I have a matrix that I would like to write to a text file. I need however to add a title and some comentary at the top of the text file before the matrix I have is written. I can't seem to find a method to do this. Any Suggestions? Thanks ... 11 May 2010 15:38

How to Identify 3D position of a point from uncalibrated image.
Hi all, I am working upon camera calibration and have built up understanding towards projective geometry and DLT method to find out camera parameters. As we know that for calibration we need to have Euclidean structure of the object (i.e. 3D poistion of control points must be well-known) before we apply DLT. Ca... 11 May 2010 14:30

video
Hi, I am using mmreader and mplay to view some video files. Does anyone know whether it is possible to create a box that I can move around to different areas of the screen? For example, if I had a video of a person moving, I would like to move the box around, frame-by-frame, so that the box was always centered aroun... 12 May 2010 08:02

Jacket toolbox for MATLAB on GPU
Hi all Does anyone use the Jacket toolbox (by Accelereyes) for doing MATLAB computations on a CUDA (NVidia) GPUs? I notice they've recently reduced the cost of their license. Do people think it's worth forking out for? I've been using my Tesla GPU a fair bit recently for doing faster parallel computations, and si... 12 May 2010 05:52

concatenating data files
Hello, I have several data files that are all discrete parts of the same sample space and I need to concatenate them all into one big array. For example, we might have the following two files: data1.dat: 1 1 2 2 3 3 4 4 5 5 data2.dat 6 6 7 7 8 8 9 9 10 10 and I need to import them into matlab int... 11 May 2010 23:24

why mvnrnd works with a singular covariance matrix
Hello Matlab users, I am puzzled to know how matlab generates random vectors chosen from a multivariate normal distribution with a mean vector MU and a singular covariance matrix SIGMA. I am trying to generate large number (say 2000) of random vectors with a target MU and SIGMA. I develop the MU and SIGMA from a... 12 May 2010 05:52
