SimPowerSystems sources
Hello! Can you please tell me what data type I need for the elements in the SimPowerSystems. I'm trying to connect a source (from simulink/sources) and none gets connected. The same is valid for a signal from wrokspace. I can only use the elements with the sources given in SimPowerSystems? Thanks a lot! ... 9 Jun 2010 06:25

sets of subsets generated by 'permpos.m' --- looping?
Hi there, perhaps, someone can sort me out? Assume you have a set of J objects, and you want to generate all possible (permuted) subsets of size j = 2, ..., J-1 selected from the set of J objects (the subsets should at least contain 2 objects, and the set containing all J objects is trivial) --- I used the "perm... 8 Jun 2010 10:17

approximate hessian after ktrlink
Hi! Does anyone know how I can approximate the hessian from a maximum likelihood after using ktrlink (which is similar to matlab's fmincon) to get the parameters? (this is so that I can get the standard errors). Thank you!!!! ... 8 Jun 2010 05:49

signed distances from SVM hyperplane
Hi all, Using svmtrain/svmclassify I'm returned the class labels. I additionally need the distances from the SVM hyperplane to derive a confidence value for the classification from that, ... So, is there any way to get the distances from the SVM hyperplane? An example how to do this would be great - like e.g... 10 Jun 2010 08:52

Efficient reading of binary complex I/Q values
I need to read in a binary file with real (in phase) and complex (quadrature) values of 4 bytes each. Is there a quicker or more memory efficient way of reading them in and converting to real than this? I need to read in very large files and I'm running out of memory before this completes so I'll probably have to a... 9 Jun 2010 02:05
