remove scientific notation from plot axes
Hi everyone! Is it possible to remove the "x10^y" from the x axis when handling a large variable? example: x = zeros(1:220500, 1); plot(x); axis([0 length(x) -1 1]); set(gca, 'XTick', 0:length(x)/10:length(x)); thanks ... 18 Apr 2010 16:23

fmincon with interior point - honoring bounds
Hi. I'm trying to run a problem of the type min f(x) s.t. g(x)=0 . And I would like to optimization routine to honor g(x)=0 at each iteration. I've set the options to run with the interior-point method and the honor constraints option. Nevertheless the optimizer violates the constraint (feasibility error is not 0). And... 20 Apr 2010 18:29

MatLab Kmeans and large data set
Hi, Matlab's kmeans runs excruciatingly slow on large data sets (e.g. 128x10000). Is this normal or am I doing something wrong? [idx centers] = kmeans(discriptors' ,250); (disriptor is 128x10000) I tried increasing the number of centers in the cluster and also tried increasing the , MaxIter to 500, be... 18 Apr 2010 14:10

finding root with bisection method
hi, that's the problem 0.015=(4+x)/(42-2x)^2*(30-x) and that's code i wrote %0.015=(4+x)/(42-2x)^2*(30-x) %x=-8:0.1:4; %y=((4+x)./(42-2.*x).^2).*(30-x)-0.015; %plot(x,y) %grid clc;clear; x0=-4; x1=-2; fonk=@(g) ((4+g)/((42-2*g)^2)*(30-g))-0.015; err=1; while err > 1e-2 x2=(x1+x0)/2; if feval(f... 17 Apr 2010 17:25

alligning columns in a file
Hi, okay I have now done the legwork of manipulating all the datasets and generated a nice 300 x 300 cell array of numbers but they're classed as characters even though they actually numbers. I have now printed this array into a file, again in the same dimensions as my cell array, however, even after trimming each an... 17 Apr 2010 17:25

Spectral content of a time domain file
Hi, I have a time domain data file which is acquired by a 100MSample digitizer. The data file has 10000 samples of the data. I only want to see the spectral content of a part of the data. I have the following code. I will appreciate if someone tells me this is alright or am I missing out on something or doing something... 17 Apr 2010 16:18

Full-BEKK MGARCH
Hello Fellows, I am trying to estimate Full-BEKK model in OxMetrix,but unfortunately it computes only restricted versions i.e. Scalar and diagonal.I was told that Matlab is capable to do this.Does anybody have a code for the 4 variable(3 or 2 is ok as well) MGARCH model. Thank you guys! ... 27 Apr 2010 19:03
