transform arbitrary 3-D scattered points into a sphere of points
I realize this isn't a technical question per se, but I think that some of you may have some insight into this type of problem. I have a set of x,y,z arbitrarily scattered points/particles that I would like to collapse into a sphere containing the same number of particles, all are on the same 3-D grid with no ov... 6 May 2008 23:26

need explanation: something that works with \ operator doesnt work with lsqnonlin function
Hi, I have a LINEAR problem that I can solve using \ (slash) operator. I need to solve a NON_LINEAR version of this problem. For this I suppose I should use LSQNONLIN. I tried to use it and it doesn't work. I then tried for debug to plug into LSQNONLIN my linear problem and it doesnot work as well. Do... 6 May 2008 22:22

what is better to use: fmincon OR lsqnonlin
Hi, My objective function is to minimize the L2 norm of some vector + I have a linear constraint on the variables. So the output of the objfun: 1) in case of using lsqnonlin: F = [ f_1 ; f_2 ; .... ; f_n ; A* f - b] 2) and in case of fmincon the output is: sum ( f_i.^2 ) with the constraint A... 6 May 2008 23:26

Object Oriented Changes in 2008a
Can anyone point me to a list of the specific changes between 2007b and 2008a with regard to support for object oriented code? I written some MATLAB code using 2008a that takes advantage of the latest object oriented features and I just discovered it also need to run in 2007b and I'm see initial errors cal... 6 May 2008 23:26

Temperature and pressure model of optical spectra
Hello, I'm working on a project to autocalibrate my optical spectra based on temperature and pressure. I have a full designed experiment dataset for temp and press on my system and can generate PLS regression models from these spectra. I have even been able to generate PLS2 prediction models for these data tha... 6 May 2008 22:22

Unix time to datenum
To convert from Unix time to Matlab, use the following: datenum([1970 1 1 0 0 unix_time]) where unix_time is the unix timestamp. This works quickly and consistantly for me!

Guide and STK
I am working on a project that requires using STK toolkit to show the data. I have been able to send commands from Matlab to open and activate STK. But when I try to use Guide, it gives me the message that No License is found. I have been in touch with STK application analyzers and have checked the STK licens... 6 May 2008 22:22

Creating figures larger then screen
I'm trying to create a figure that is larger then the resolution of the underlying screen. The screen's resolution is 1280x1024. I'm trying to create a window that is 1280x1050. The purpose for the larger window is to hide the title bar off-screen (this is for a turn-key application with its own custom desi... 6 May 2008 23:26

Cutting down a polar plot to the first quarter
Is there a simple way to cut out the first quarter from a polar plot? I am only interested in the region from 0 to pi/2; the rest is just taking up space. How can I crop the plot to this quarter? Example plot: a=0:.1:pi/2; polar(a,sin(2*a)) ... 6 May 2008 22:22
