to find a certain value in an array
I have an array named th actually it is a structure, so the values of th is in th.signals.values but i guess that is the same thing. the numbers in th are increasing and i want to know when the first certain value occurs. to be more exact i want to know what position in the array the holds the value 8400, howeve... 1 Jun 2010 11:57

solving a system of COUPLED partial differential equations
"Hello, I'm trying to solve a system of 3 partial differential equations (3 diffusion equations, 2nd law of Fick) using ode15s! First of all, I transformed my system in an ODE system using the finite difference method to discretize each equation. After, I attached the boundary conditions , that after the discretizat... 1 Jun 2010 10:50

fmincon penalty ODE
Hi there, I am trying to minimise an objective function after solving a set o ODEs in each iteration. The parameters that define the ODE has bounds and these are the inputs to the fmincon function. Now, I would like to additionally penalise the objective based on some state variables at the end of my ODE integration. ... 3 Jun 2010 07:49

External API matOpen not producing compressed MAT file
I have a legacy C program which takes a proprietary data file and converts it to a .mat. The systems I have to run on are HP-UX and Solaris 9. Matlab version is 7R14 SP2. The C program is being run OUTSIDE of Matlab, so MEX is not an option. I know I'm stuck with ancient tech here, but that's all I have to work w... 1 Jun 2010 09:44

Deleting Duplicate XY Data from 3d Matrix
Hi all, I have a set of XYZ data that I am looking to remove duplicate (X,Y) values from. I am currently using the Unique function to remove the duplicate data, however this function does not allow me to specify which data to keep/remove. Z data that is equal to 0 signifies a dropout of data, so I do not want to... 1 Jun 2010 09:44

Adding French Accents to my .fig files
I have to add the French translation to my Matlab .fig files. These are the characters for ' and ` as well as ^. Does anyone know how this is done? I've tried the \^, but it just raises the character to a superscript. ... 1 Jun 2010 09:44

How do I align two time-stamped data streams?
Hi all, Here are the data I am working on: dDataTmp1 and dDataTmp2 are two Nx2 matrices, with the first column being the timestamps and the second column the data. For example, K>> datestr(dDataTmp2(1, 1)) ans = 01-Apr-2010 00:19:00 They have two properties: 1. They are gigantic. 2. They are no... 2 Jun 2010 07:38

web application of matlab with php command system
Hi, I have to develop a website that enables the execution of a matlab program. I would like to know whether or not the option I am trying to implement is feasible and/or if this depends on the type of license that I have. In particular, I would like to be able to lauch a script from php in this way: system('./s... 1 Jun 2010 11:57

Data transfer between mxArray and mwArray
Hi All, I am new to Matlab so... my question is about getting data to\from Matlab Compiled (to C++) Libraries. I use mcc command to create several different compiled C++ libraries - Matlab Compiler produces several functions in a *.h file for every library which I include in my project and it works fine. However, I... 1 Jun 2010 08:38
