Plotting on a circle
Hi all, probably a pretty simple problem but can't figure out how to go about it myself. I have a user who will be the center of a network. I will be locating this user at a point say, for convenience the point 0,0. I will then have a number of different users (will vary each time) who I want to plot lines to or ... 24 Jun 2010 10:43

Inherit sample time for constant blocks
Hi! I am working on a Simulink-model which contains blocks which should run with different sample times, the model is later downloaded to rapid-pro unit (but that is another story). In the simulation settings in I have entered the fastest sample rate, then I use rate tranisition blocks to specify a lower sample ti... 28 Jun 2010 03:01

Simulink Queue Block vs Buffer Block
Alec Rogers <alec.rogers(a)mathworks.com> wrote in message <hi28k3$ipk$1(a)fred.mathworks.com>... Hi Corey, The Buffer block changes the size (and therefore the rate) of a signal. It does this in a constant way, and it only stores as much data as is necessary to perform the conversion. The Q... 24 Jun 2010 08:30

read xls files with name 00000.xls and 00001.xls
Ok tnx for rour reaction, but how/where do I put the n=n+1 part? Because all of the variables (except len) are char and you'll still have the same problem... Or I don't really understand your solution ;) And an elegant solution or not, that doesn't matter. If it works, i'm fine! :) "Ulf Graewe" <ulf.graewe(a)io-war... 24 Jun 2010 07:26

Structures or something else
Hi folks, in a loop, I need to load a set of variables (of type matrix, double) and do some stuff using a function that takes the first variable and each of the remaining variables as argument. It would be fine to take it in a loop. Normally, I use S = load('filename', 'apple', 'cherry', 'kiwi' ... ) However, if ... 24 Jun 2010 11:50

Precision of CLOCK and CPUTIME
Dear readers, I need some nearly random bits to create a nearly unique number equivalent to a GUID. I thought CPUTIME or CLOCK would be fine, but I found some unexpected correlations, when I call this function repeatedly. % Tested on Matlab 6.5, 2009a, WinXP 32bit function sillyTest a = cputime; v = rand(1... 26 Jun 2010 04:23

convolution matrix
hi Steve convmtx2 takes a filter (in the form of a 2-D matrix) and returns to you a convolution matrix. This matrix can be used in a matrix / vector multiply to perform 2-D convolution. I have image in stack form in 3D I want a convmtx3 like function which will takes a filter (in form of a 3-D matrix) and re... 24 Jun 2010 06:21
