I need help vectorizing my code please
In my simulations these loops need to be run through almost 200000 times. With my clumsy programming I estimate that this will take almost 20 days! I would really appreciate some help in vectorising and hopefully optimising this chunck of code (below) Thanks! %Y, A and O are matrices %c and ... 24 Jun 2010 20:49

floating point help!
Hello, I'm having an FP issue that's sort of driving me crazy. I'm doing some division by 10, subtracting, and taking a floor. Purely mathematically, this is exactly what I want to do: ------ num = 12; a = num/10; b = floor(a); c = a-b; d = 10*c; finalResult = floor(d); ------ However, these are the res... 24 Jun 2010 18:35

FMINCON Message
Hey,I was doing a minimization problem in which I was using FMINCON function to optimize my objective function.For a certain value of k the number of constraints would change and the number of variables would get bigger. For k=1, the program is running and giving me good results.When k=2,3...and so on the program ru... 28 Jun 2010 09:29

save workspace AND figures
Hi all, I understand how to use SAVE and LOAD to save/load the contents of the workspace. Is there a quick way to also save any open figures? It would be nice to be able to load a previous workspace and also have the previously open figures also re-populate. Anyone know of a function to do this? If not, I'll tr... 23 Jun 2010 19:31

Hi all, I have thirty 10min mp3 recordings. Using a certain program I marked the start and end points regarding whether a person is talking or not. These start and end points are content of i1 and i2. Audiolabel contains the labeling of each sequence, i.e. 'speech' or 'nonspeech'. This is an example of the struc... 23 Jun 2010 19:31
