Matlab

how implement the following equation.
I am facing problem in understanding this equation: b sub(x,y) = min sub(p) med sub (t) (I sub(x,y) and superscript(t) - p) power 2 where I represent a sequence including N images.p is the background brightness value to be determined for the pixel location (x,y), med represents the median value, and t rep... 29 Jul 2010 06:24

Accelerator - shortcuts on MAC
Hello... How can I suppress the global MAC shortcuts when I incorporate 'Accelerator' keys into a MatLab GUI? Worls perfect on the PC, but on MAC command+M will minimize the GUI instead instead of calling the Callback for command+M in my GUI... Thanks Felix ... 5 Aug 2010 10:13

plotting parts of a 3d matrix in 2d
Hi, I have a 3d matrix (x,y,z) and I want to be able to check how one component changes as we go through the x axis i.e. I want to look at the components (1,1,:), how do I do this? ... 31 Jul 2010 21:37

Frequency generator : NI USB 6211
Hi, I am using NI USB 6211 card in my application for analogue voltage measurements. I am using external pulse generator of 20 kHz to trigger the circuit. It seems that there is a DEDICATED square pulse generator built in to the card. It is a great help if someone could help me to make use of that dedicated pulse gen... 29 Jul 2010 19:36

frame based integrator
Hi I've to use the discrete integrator, but I'm working with frame based signal and this block doesn't support frame. any suggestions? (I need the discrete integrator's option ("upper saturation" and "lower saturation" that I couldn't recreate with my owm integrator) tnks marco ... 29 Jul 2010 04:14

Two set of eigenvalue equations
Dear Friends, Please, help me to solve the following problem. Any hint or comment would be thankful. I have two expressions: 1) One is Determinant (4X4), which contains two unknown variables (x1,x2). 2) Another is some expression f(x1,x2). I would like to find solution (x1,x2), which satisfies: Det=0 and f(... 29 Jul 2010 09:40

Problem with parfor
Hello, I'm trying to speed up a for loop in a Matlab program using parfor. The problem for loop is as follows: coupled_data = zeros(1, length(e)/segment_size); parfor i=segment_size:segment_size:length(e) coupled_data(i/segment_size)= bin2dec(num2str(data_e(i-segment_size+1:i)))+1; end I get the following... 29 Jul 2010 04:14

custom file extension
I'm making a graphical interface for a Simulink model, where the user is to define a large number of parameters for different vehicle configurations. Instead of saving a whole simulink model for every parameter set entered, Im going to save the user's parameters in .mat file. I just wonder if it's possible to ... 29 Jul 2010 08:34

What are the limitations of hinfsyn?
The problem is that your plant contains a pure integrator. The algorithm of hinfsyn is unable to synthesize a controller for such plants. To be able to synthesize a controller you should shift all poles of your state space model a little bit to the left half plane (about 1e-3), synthesize the controller for this plant... 29 Jul 2010 04:14
