matlab crash and session logout in suse 10.2
"Sergey " <fakeEmail(a)gmail.net> wrote in message <hi8imu$ab1$1(a)fred.mathworks.com>... I got an official reply from mathowrks. This appears to be a problem with the opengl driver on linux. Short of installing the bug-free driver, the only other option is to set opengl to software at the begging of each matlab session... 12 Aug 2010 15:52

Global optimization question
I have never used the golabal optimization toolbox and i am facing problems in running the global search. I am trying to minimize the function WargaNSTR3 (Loss=WargaNSTR3(b,Qtc)) Loss is the difference between theoretical and actual prices. So I am trying to minimize the difference between the prices . The theoretic... 13 Aug 2010 19:03

Extract Data from String
I need to extract data from a string. An example string array is below: 'il_mh_row1:9' 'il_mh_row1:10' I need to extract all numbers after the :, and there may be 1 number or 3 numbers following the colon, depending on the case. I want to store these numbers in an array once I pull them out of the string. How... 12 Aug 2010 18:04

Problem with timestwo.F example in 64-bits?
I seem to be having trouble when compiling the timestwo.F example provided in MATLABROOT/extern/examples/refbook. I am using R2010a, 7.10.0.499 on a Mac with OS X 10.5.8 on, so this may have to do with the 64-bit thing. First, a question: timestwo.F is supposed to work for 2x2 arrays, correct? Assuming t... 12 Aug 2010 16:59

quiver in Matlab
Hi all, I am now using the quiver to generate a vector plot in Matlab. The plot come out nicely except for the plotting position. Let say for a vector on point (x,y), it will plot the tail of the vector on the point(x,y) I have did some search in the help and google , but I still don't know how to plot the vec... 12 Aug 2010 14:46

dumping variables to structure
Is there a quick way to dumping a collection of variables to a structure, using the variable names as the structure fields? The "load" function basically does this somehow? Sorry if this has been answered, I'm just finding a solution quickly. i.e. clear a = 'adsf' b = rand(10); x = var2struct(a,b) x.a x... 12 Aug 2010 16:58
