fminsearch - 100 iterations when starting point is the optimum
Hi I'm optimising a function that uses a 6d variable using fminsearch. Even when I give the starting point as a known optimum, it still takes more about 130 iterations to spit out the solution - which is of course the same as the starting point. For example if I start with, X0 = [320.000 491.7420 372.6962... 5 Feb 2010 02:51

libactivation exception problem on OS X
I had this problem as well, except on Snow Leopard and with r2009a. Since no one followed up, I wanted to confirm that Java was indeed the culprit, but I didn't need to use 1.5 -- instead I needed to set 32-bit mode to be the default instead of 64-bit. Using the Java Preferences application (in /Applications/Utilities)... 24 Feb 2010 10:50

what's the best way to find the number of consecutive blocks in
Dear Luna! I want to find the length of longest consecutive stripe in that column... You can find the indices of changes between the values with: Ind = find(diff(x)) Then you can find the number of elements between the changes with a further DIFF: Len = diff(Ind) Now [Num, MaxInd] = MAX(Len) ... 26 Jan 2010 18:55

what's the best way to find the number of consecutive blocks in an array?
Given an array A, for each column, I want to find the length of longest consecutive stripe in that column... for example, a column is as follows: 1 1 1 0 0 1 -1 -1 Then the length of the longest stripe should be 3, because there are three 1's out there...
