Need help at matlab, school project.
Hello everyone, i'm developing a school project in matlab, that consists in the "Simplex algorithm" for mathematical optimization. I found out that the rref command can help me, but not actually help me. The simplex algorithm is basicaly the same process that rref, except for one thing, the rref does its process with all the lines in the matrix, the SA need it at n-1. I don't if had been clear enough, so last shot. Let's choose a rando matrix. 1 2 3 So, doing the first step with the first line it should look like this: 1 2 3 4 5 6 ...

Newbie in matlab...need urgent help!!
I am trying to implement a bandpass filter on a signal data, xx. It is of 200,000 samples and the sampling frequency is 40 kHz. I am using a butter filter function and my program is as followed: HalfFs = Fs/2 Wp = [1000 1550]/HalfFs; Ws = [950 1600]/HalfFs; Rp = 3; Rs = 40; %Calculate the minimum order of Butterworth filter [n,Wn] = buttord(Wp,Ws,Rp,Rs) [b,a] = butter(n,Wn); yy - filter (b,a,xx); xx = conv(xx,yy); my program always hang upon the convolution step...does anybody knows how to solve this problem? silverlex wrote: > > > I am trying to implement a bandpass filt...

Matlab plots outside Matlab
I'm making an end-user application where I would like to use Matlab functionality both for calculation and plotting. Matlabs GUI builder guide does not satisfy my needs (no support for f.ex. internal frames and other nescessities), so I'm planning to compile my Matlab code and use other API (Java, QT or something) for GUI. My problem is then, that I loose access to the neat plotting commands availible under matlab GUI... Is there a way of integrating Matlabs plot functionality into another GUI system? - has it been done? - I appreciate any response! - P�l Berge ...

Calling Compiled MATLAB from MATLAB
Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

Hi there every one I need some help with the following function: function cc = find_cc(n) global nu cc(1)=(-8.*i.*nu1-3.*n.^2-5+4.*i.*nu1.*n-4.*n)./n./(-n-2+4.*i.*nu1); cc(2)=(3.*n.^2+2.*n+4)./n./(-n-2+4.*i.*nu1); cc(3)=-(n-1).*(n+1)./n./(-n-2+4.*i.*nu1); end where \nu is abitrary variable. cc(1), cc(2) and cc(3) are entries of a cc(3,1) matrix. Each time I run the above function I get the following message: "In an assignment A(I) = B, the number of elements in B and I must be the same" I guess the problem here is \nu because if I set \nu to 1 the it works.

Trying to import multiple images into MATLAB and treat them as frames and overall help with matlab
Hello.I'm in desperate need of some help here, I want to import various images of clouds taken about 30 seconds in one another as a single video file the loop I used to originally do this consisted of: files = dir(Directory of files) for i = 1:100 str = strcat('Directory for workspace',files(i).name); clouds(i,:,:,:)=imread(str); end; But the images it produced were 4-d uint 8 and i was unable to read them or work with them at all. Please can you offer me some type of solution. The main goal of these processed cloud images is to be able to track the movement of clouds in the skys so if you have any demos that I could look at please post them On 28/12/10 8:49 PM, Linus Hamann wrote: > Hello.I'm in desperate need of some help here, I want to import various > images of clouds taken about 30 seconds in one another as a single video > file the loop I used to originally do this consisted of: > files = dir(Directory of files) > for i = 1:100 > str = strcat('Directory for workspace',files(i).name); > clouds(i,:,:,:)=imread(str); > end; > > But the images it produced were 4-d uint 8 and i was unable to read them > or work with them at all.
