Fmincon fun and nonlcon functions
Hello everyone, I m using "fmincon" to optimise a problem. The function evaluations have to be done by an external program which produces an output file that can be read by "fun" and "nonlcon". I wonder if this external program has to be called both by "fun" and "nonlcon" functions, or whether I can only call it onc... 13 Aug 2010 11:23

Is it Ok to shrink with [ ]?
Dear all, I know that growing with indexing, clear x for i=1:10 x(i)=1; end, is not recommended. My question: does shrinking with indexing, x=ones(1,10); for i=1:10 x(1)=[]; end, cause memory problems? I.e. does Matlab reallocate memory for variable x every time x(1)=[]; is executed? ... 13 Aug 2010 11:24

LeGall 5/3 Wavelet
Hi I am planning to implement a LeGall 5/3 wavelet in the lifting form on a DSP chip. I have looked through a few papers and have the two equations I need for the high and low pass output for 1D. I would like to run the wavelet in Matlab so that I can compare the output of my DSP and verify it. Can someone tell me t... 13 Aug 2010 10:17

filter design
I was asked to design a BANDPASS filter by this istruction: "2-stage 4th order filter with Q=4 and 12dB/octave high-pass and low-pass rolloffs". But I don't really understand what I am asked. Is this band pass made of a 4th order high pass followed by a 4th order low pass, and Q is the quality factor which defines th... 13 Aug 2010 07:02
