randperm in m x n array with different randperm(n) by row
Hello All I'd like to randomly reorder an array of arbitrary size m x n but keep the elements that are in row m_i in that same row. in a for loop it would be something like for i=1:size(array,1) holder=array(i,:) array(i,:)=holder(randperm(size(holder,2))); next i is it possible to use randperm to generate... 23 Apr 2010 20:59

Nullpointer exception when calling javabuilder class in Mac os 10.5.8
Hi I recently wanted to compile and run javabuilder components on a Mac (OS X.5.8). However I continuously get the following exception as soon as I want to instantiate a Matlab related class (see test code and exception at the end of the message) in my Eclipse environment. CONFIGURATION: MATLAB: - Matlab 2009... 30 Apr 2010 18:32

find higher values
hi, I have a matrix and I would like to find the position (indexes) higher values (for example the 50 higher values). Is it possible to do it directly? (for example with the "find" command ?). Thanks in advance! Rodrigo ... 23 Apr 2010 20:58

switching variable in ODE45
Hello, I've developed a model using the ODE45 solver. It worked fine, but now the solver has difficulties with a switching variable. I used this variable from the beginning and had no difficulties with it before. Here is a simplified summary of what happens: if Y1 < Y2 then R = x, else R = y dV1dt = Y3*C + Y2/R ... 23 Apr 2010 20:58

hough transform circle detection
Greetings, I should preface this (as I do all my posts) by saying I'm still a rookie at image processing. I submit this to any of you gurus who have the time and attention to spare. Sorry this is so verbose: I'm trying to automate what we call a Winston-Lutz test, where we shoot radiation through a circular con... 23 Apr 2010 20:58

simulink and arduino
I'm having problems with serial communication between simulink and arduino. I am trying to read joystick input and send it to arduino. I chose simulink becouse it's simple to read joystick input, it only takes one block. I could do using c++ program, but my knowledge in c isn't nearly good enough. So, in Simulink, I... 23 Apr 2010 21:00

Constrained annealing solver in MATLAB
Hi, I need to simulate an optimization problem with annealing algorithm, but it is constrained optimization. Does MATLAB have constrained Annealing Solver? I could find only unconstrained Simulated Annealing Solver in MATLAB (R2008), i,e. simulannealbnd. If you know please mail me... Thanks for help, ... 23 Apr 2010 20:58
