histc
hi, i have a vector containing n elements. Mean and std of data is unknown. I want 2 segment data on basis of clustering. e.g, h=[0 97.9501 97.2311 97.6068 97.4860 97.8913 112.0000]; [n,]=histc(h,[min(h):1:max(h)]) %%%% assuming std 1 i got 5 elements which are grouped together. How can I have cluster ... 16 Jan 2010 18:20

compare two cells not minding the order
Hello I am looking for an easy way to compare two cells of strings. for example a={'aa','ba','c'} b={'c','ba','dd'} and I want the function(a,b) to return someting like [0,1,0] as the first and the third strings of the first cell don't exist in the second. the function strcmp() minds the order which is not suitable... 17 Jan 2010 07:15

optimization problem in KF and MLE for state-space model
Hi, everyone, I have some problem on the optimization during the maximun likelihood estimation for state-space model via Kalman filter. There are around 100 parameters to estimate. 1. fminsearch works, even it is very slow. 2. fminunc, cannot work. It always stops by the error of the covariance matrix of ... 18 Jan 2010 08:37

varargout{1:nargout} = mexFunction() does not work
I have tried to find some documentation regarding using the varargout mechanism with mex functions. Perhaps I did not look hard enough, but I have not seen any discussion of why this seems not to work. I wrote a simple test function that creates the same number of dummy outputs as the value in the nrhs argument in mexF... 18 Jan 2010 13:07
