how to visualize w=f(x,y,z)
Dear ALL, in 3D space, (e.g., x=1:1:100,y=1:1:200,z=1:1:400) at every combination of (x,y,z), there is a W value it is like If I have a 3-D object, which has a nonuniform mass density w at coordinate (x,y,z) how can i visualize the mass density, w(x,y,z), of this 3-D object? Thanks a lot. Andy ... 17 Jun 2010 02:27

Editor error link behaviour bug
Hello, I'm using MATLAB R2009a on linux. When using the editor ( I use the editor undocked from the main matlab console etc.), should it detect an error, such as a missing parenthesis or something, the error is underlined as usual. When I then mouse click on the place where the error is I am switched back to the mai... 7 Jun 2010 09:38

Nelder-Mead algorithm
Dear I use fminsearch (Nelder-Mead algorithm) as optimization algorithm in a non-linear least square peak fitting application. Now, I am investigating the algorithm, but the simplex method isn't very clear to me. Will this method generate new points (extrapolate) or just use the points from the function (curve)? ... 8 Jun 2010 10:17

Catching incoming modal dialog
Hi, Is there any way to catch incoming modal dialog box (and close it)? I can't disable the dialog box because its part of pcode which cannot be changed and need to be used. I currently use timer in the code, but the execution of timer within another timer cause problems (and won't execute), so I'm looking for ... 6 Jun 2010 11:36

GUI colors Linux
I wondered if it is possible to change the colors of the graphical user interface of the MATLAB desktop on Linux. The current beige color scheme doesn't really appeal to me. I've searched my MATLAB directory for the hex code of the background color (#ece9d8) but without any positive leads towards a configuration fi... 6 Jun 2010 11:36

metadata export for matlab calculations
I wonder if anybody's got any tips on this: I'm trying to automate the import of metadata information on scales and offsets from a file, so that I don't have to keep cutting and pasting that information from hdftool into the program I'm writing. At the moment I don't know how to use a Matlab command line to do this a... 6 Jun 2010 13:48

fastinsert error: 'setDouble'
Hi All, I am currently writing a generic script, to commit structure data in database table, and when finished I hope to have a function for this job. For a still unknown to me reason, when trying to import the data to the database table (which are converted before import to a cell array) I get the following mess... 6 Jun 2010 11:36

convolved audio cut in half and plotting problems
hi all, i've got two problems which i assume are quite common and also easily fixed, but i don't know how. my first problem is that i'm running Stephen McGovern's room impulse generator and fconv function with conjunction with each other on a standard short speech wav file. the problem is the output is cut short, an... 6 Jun 2010 19:27

timer execute within another timer?
Hi, Is it possible to execute a new timer within another timer? When I try to do so, the new timer won't run until the "ancestor" timer finish. Any way that the new timer will execute in parallel with its parent timer? In code: I get to the %Not row before I get to the %Desired row. the 'Got Here!' message ... 6 Jun 2010 11:36

How to set the seed as a 128 binary string of psudo random numbergenerator (randn)
Randima Hettiarachchi wrote: I'm doing a research, which requires to seed the pseudo random number generator with a 128 bit binary string (eg. 11001101) and obtain a vector of 1000 random numbers. You will have to implement your own random number generator, as that is not possible in Matlab. Matlab... 7 Jun 2010 09:38
