obsolete function
I was running some code that seems to run only in older versions of Matlab: Function "mxGetJc_700" is obsolete in file ....(64-bit mex files using sparse matrices must be rebuilt with the "-largeArrayDims" option. See the R2006b release notes for more details.) Is there any ways to fix this problem? (the matlab I'm... 5 Jul 2010 17:45

Normalized frequency conversions
Matlab explicitly states that: "All of the non-object oriented filter design functions operate with normalized frequencies. Convert frequency specifications in Hz to normalized frequency to use these functions. The Signal Processing Toolbox software defines normalized frequency to be in the closed interval [0,1] with ... 5 Jul 2010 16:39

Simmechanics revolute joint contraint
Dear all, I am having problems with my simmechanics model. The model is kind a like a flight simulator (Stewart platform like Matlab example) only with some differences. So it has a body which is carried by 6 legs forming 3 'diamond shaped' supports with only revolute joints. The problem is that I obtain the foll... 5 Jul 2010 15:31

Converting optimset and fminsearch to C code
Hi, I would like to know if there is any method by which I could convert optimset and fminsearch functions into a C/C++ code. Since i need to parallalize my code I need to convert these functions. Any help would be really appreciated. Regards, Tejdeep ... 5 Jul 2010 14:25

Removing Square brackets from my text
Hi everyone, I came across a problem and I am unable to workout even after trying with textscan,fscanf, and whatever i can.. I don't know where I am doing wrong. I have a software that would generate my simulation results in this format, [[0.990272;0.108886;-0.0866375],[-0.108472;0.994054;0.00949007],[0.08715... 5 Jul 2010 15:32

Large linear system
Hi, I need to solve a linear system Ax=b with A being fat and sparse. However, the size of the matrix is very large. How can I solve x efficiently, such as using some iterative methods? Furthermore, are there any methods to solve the out of memory problem, for example, storing the nonzero elements of A? Thanks a ... 5 Jul 2010 23:14

Pattern in a signal
Hi, i have a big signal (corrupted by noise) in which i should find a pattern. I have read something about using xcorr but i do not exactly how to use it. what should i look for in x = (xcorr ( pattern,signal)) ? My pattern will be 7 square pulses with a frequency of 1040 Hz Please let me know how to use ... 6 Jul 2010 12:15

Can Kalman Filtering be used in non-time applications? Updating Models
See Subject. Actually, my interest is in updating non-linear models whose data might be collected in batches. None of it is time related in the sense of observations occurring in a time ordered sequence. It's a situation where it takes hours to collect and build the model, then have new information available at... 5 Jul 2010 13:18

How to align dates in Matlab fast?
Hi all, I am currently using some "for" loops in doing this and as I am reviewing my programming, I don't like it myself. So the question is how to align dates fast in Matlab. The inputs are: ReferenceDates, MyDates, MyData, where "MyDates" and "MyData" have the same number of rows, and "MyData" can be an ar... 5 Jul 2010 14:25
