Problem with BIC
Hi, I need a help with BIC algorithm I implemented the BIC as explained in Scott. Chen " Speaker, Environment and Channel change detection and clustering via the bayesian information criterion" paper and my code is not give the right value. For example I need to send 2 segments and the BIC value must be <0 if the... 2 Jul 2010 17:57

fmincon
Hello I am using fmincon to minimize a problem with an input variable x and an auxiliary variable w. How can I call fmincon in order to get the results for both x and w? The function that I have is a function with simple linear constraints. The auxiliary variable told me that will make the optimization better. Help pl... 2 Jul 2010 21:14
