rescaling for fmincon
Sorry if that was unclear, the objective function m-file takes 1/variance as the input, but i define an anonymous function that takes s.d. as an input and feed this to the solver. In retrospect this information was irrelevant. "Matt J " <mattjacREMOVE(a)THISieee.spam> wrote in message <i2nk6k$k6b$1(a)fred.mathworks.com... 27 Jul 2010 19:29

rescaling for fmincon
"Samuel Edwards" <DJeter1234(a)AOL.com> wrote in message <i2nauv$bfo$1(a)fred.mathworks.com>... I am running a least squares minimization with fmincon to solve a least squares problem. Essentially, a 5-tuple of parameters maps to an 8-tuple of percentages. The parameters are of the form (mean, 1/variance1, 1/variance2... 27 Jul 2010 18:22

Strange Filter Behavior?
I'm noticing strange patterns in a bandpass butterworth filter (order 4, cutoff frequency .25/30, 2.5/30). It seems that there is a sort of sinusoidal ringing that fades to zero after about 30 sec. at both the beginning and the end of the data, where the values should be zero. The especially strange part is that the pa... 2 Aug 2010 13:39

An exact simplification challenge - 99 (EllipticK/Pi)

rescaling for fmincon
"Samuel Edwards" <DJeter1234(a)AOL.com> wrote in message <i2nauv$bfo$1(a)fred.mathworks.com>... I have rescaled the problem so fmincon inputs (mean, s.d.1, s.d.2, s.d.3, constant) with a neutral starting guess of [0,1,1,1,0]. I run fmincon, and then rescale by the last guess so that fmincon starts at [1,1,1,1,1] and ... 27 Jul 2010 18:22

Fixed point number truncation ... Help !!!!!
Hi, I have a signed fixed point number N1 with 11 bits wordlength 9 fraction bits, and I need to truncate N1 to obtain a signed fixed point number N2 with 8 bits wordlength 6 fraction bits, it is, N2 is N1 but without the 3 LSB bits, here an example: N1 = -0.0020 DataTypeMode: Fixed-point: bi... 27 Jul 2010 19:29
