MATLAB code for fitting ARMA/ARIMA models?
This is correct. Also note that you can specify a differencing order using DIFF(X,ORDER) based on the trend (stationarity) observed in your data. And remember too if you do forecasting this way that you have to integrate the resulting predicted time series by recursively summing the predicted values using the l... 23 Dec 2009 20:44

thresholding with connected components
Hi everyone, i'm newbie with matlab. I'm working with image processing tool and i try to realize a script that takes the image of a plate number and returns the segmented image. This is based on a program that i found here. My problem is this: i have generated the segmentated image but i have a large number of conne... 23 Dec 2009 13:43

Tanengrad (Tanenbaum`s Method)
Hi everyone! I am trying to implement the Tanengrad algorithm in matlab. It is a quantitative measure of the quality of an image (contrast). I took some pictures from papers, where this method is discussed, to have compareable measurements . (http://books.google.de/books?id=Phlog9JD-uQC&pg=PA73&lpg=PA73&dq=tenengr... 23 Dec 2009 13:43

shift direction using correlation
In case 1, signal2 should be right shift by 2 to be same as signal1. In case 2, signal2 should be left shift by 2 to be same as signal1. For the ease of programming, I expect dshift can have a sign to indicate the shift direction. The method I am going to use is: If (dshift < length/2) actual shfit = dshif... 23 Dec 2009 13:43

Fitting polynomial to a surface
Hello, I am wondering if someone can help me to fix a problem I am having in financial mathematics. I have a myfun() implemented and I want to calibrate its parameters to some data. myfun() has the following form: myfun(X,T)=a+b*exp(c*T)+d*X+e*X^2+f*X^3 the data with which I want to fit myfun is a surface. I... 23 Dec 2009 13:43
