How do you know when you are debugging?
In many languages, it is possible to know while executing the code, if the code is currently being debugged or not. Is there a built-in Matlab mechanism for the program to know when it is running in the debugger? Otherwise I would set a global variable, but hey, why bother if it isn't necessary... Thanks. ... 8 Feb 2010 23:39

Hi. Have search already for couple hours but cannot find a solution. Suppose i have the following matrix '1-1-1999' 1 '1-2-1999' 2 '1-3-1999' '1-1-1999' 3 '1-2-1999' 4 '1-3-1999' 6 but i need it in this format: '1-1-1999' 1 3 '1-2-1999' 2 4 '1-3-1999' 6 indeed there is missing d... 8 Feb 2010 19:06

Plot gaussian contour
I have a bunch of data which I try to fit into a bivariate gaussian distribution as shown in the code below. The problem I face now is I don't know how to plot a gaussian contour to overlap on the data. Any help will be appreciated. Attached the code, X = rand(100,2) [n,d] =size(X) scatter(X(:,1... 8 Feb 2010 19:06

Prediction for ARMAX model
Hi Im having some problems calculating predictions for ARMAX model which I created. The model is modeling rougly 100 datapoints and I which to predict the next hundred or so which are unknown now. The input variables are known for the 100 datapoints which are also known and also for the next 100. What I have done i... 8 Feb 2010 19:06

Scrollable Panel
Hi. I saw a similar post a while back for creating a scrollable panel, but it is not doing what I want. I created a main container panel that contains (1) a scrolling panel (that can grown in size vertically for adding more components) and (2) a scrollbar. Everything works great and I can scroll the inner panel up a... 8 Feb 2010 15:39
