IS THIS THE CORRECT FORUM? Hope so. We have three computer networked at home...all with Windows XP. one of those is a laptop.

Hi! Using MatLab's 'movie' function you can play a movie recorded by the 'getframe' command. It is possible to specify the number of times the movie is played and the frames per second. Unfortunately, I've not found a way to stop the playback of a movie. Is it possible to, let's say I've specified the movie should be played 20 times, to disrupt the playback after an user interrupt?!

I have one question: Is Matlab's 'graycomatrix' function actually in accordance with original Haralick's 1973 paper? I mean, are they supposed to be the same algorithm? If yes, I don't think Matlab did a good job on this. For example, try it on this matrix (i.e., 'image'): 0 0 1 1 0 0 1 1 0 2 2 2 2 2 3 3 This matrix is in Haralick's original paper and the results can be compared. Can anybody ellaborate if you used it?

You do need to understand a bit about the conventions used in the software you are using. For example, the Image Processing Toolbox's default black-to-white range for double-precision inputs is [0, 1]. The reference page for graycomatrix describes in detail what it does. By default, for example, it quantizes the range [0, 1] into 8 levels, resulting in an 8-by-8 co-occurrence matrix. But for your matrix, it is seeing 5 &qu...

Hey, i have a certain outputs from a c-mex file that i need to know their mean Value before re-using them in the code.... the problem is 'mean' function is not recognized in a c-mex file... i tried to do it manually: initially sum=0; Output1= [vector]; sum=sum+Output1; mean=sum/number_of_points; problem: 1/ sum is another vector and not a single value; any suggestion would be appreciated. maybe there's a matlabmath library that recognize the 'mean' function that i should include in the code...

Is there a way to implement MATLAB's sound function under C? For those who don't use MATLAB, it's essentially a simplistic, static, mono sound function that converts a series a numbers into a sound at a given sampling rate. nothing fancy. all the Sound APIs begin by discussing all the fancy drivers and buffers and crazy shit i don't really care about.

To repeat the title, in case it is munged by Google Groups: if ('A:B:C' =~ /:(.*?)$/) then why the heck is $1 'B:C' and not just 'C' I've been developing with perl for years; but even simple things in it still sometimes throw up surprises. The regexp /:(.*?)$/ is anchored on the right by $, then comes a non- greedy match which, AIUI, is the "shortest string it can get away with", preceded by a colon. So I would expect this to pick up just the "C", as it does with /([^:]*)$/. Am I assuming/doing something silly? It is frid...

I'm using matlab 6.5 and I just realized that it comes with zip and unzip functions.

Hi... I have a foxpro program which is for producing excel reports back ended to foxpro table(.dbf). Since the table is getting bigger and bigger, it slows down my program. I need a program which can create a table archive to store last month's data which isn't needed for this month's report. Therefore, I can run that archive program once a month to save outdated data into the table archive. By doing that, I can keep my current table small. Also I will have a big accumulated backup archive table to store my old data. Thanks... Kate (yenmei20878@hotmail.com) ...

I have an existing Matlab C MEX function (walkode.dll) that returns state derivatives when called by ode23s (walkode,...) from a regular Matlab script or the command line. I would like to incorporate this into a Simulink model, and have done so using a Level 1 M-file S-function, which called walkode in the mdlDerivatives subfunction. However this model runs very slowly. I would prefer to rewrite (recompile?) my .dll as a C MEX S- function (using sfuntmpl_doc.c I believe), but I am unsure as how to go about doing so. This is where my understanding (or more aptly, misunderstanding) of C,...
