PBS Script
Hi, I have set out my PBS script within "pbsNonSharedParallelSubmitFcn" such that I can split 'n' nodes per index within the parfor loop. For simplicity, I want to run 2 simulations in parallel by an 'external' program, which is to be distributed on 2 nodes. Therefore, I would request 4 nodes in total (2 for eac... 25 May 2010 12:25

Differntiating user defined functions.
Hi, I'm trying to differentiate an expression that involves a function I wrote myself (vectrot(p, r, theta) below, which returns a vector). I want to differentiate it wrt theta, so I can minimise the angle theta. I'm giving it the following: xax = [1;0;0]; abc = [-0.57932250769383;-0.030187965400549;0.814... 25 May 2010 12:25

Plotting in the background
Hi, I have a GUI application which creates some plots. The plots consist of many elements e.g. there is a surf plot, some lines superimposed on it using plot3 etc. After the plot has been created I also manipulate the axis (axis tight, axis equal). The problem is that it is all visible during drawing, you can see ho... 25 May 2010 12:25

Subscript indices must either be real positive integers or logicals error in simple array program
Hi I'm a graduate student and studying Matlab. I have a difficulty in solving this problem. "data" is a matrix. My problem is below, for i=data(1,:):length(data) [s, r, t] = pcapro(data(i,1:12), modl, 0) end "Subscript indices must either be real positive integers or logicals." this message comes up..... 25 May 2010 11:18

Call RDF from Matlab
Hi All, I would like to call some info from RDF file to be an input for my *.m file like below: -i and j are objects that have real height (Mi and Mj) while hi and hj are height in an image which have been calculated earlier. I need to get the Mi and Mj from the RDF that I've developed as input for this segment. How ... 25 May 2010 11:18

symbolic math toolbox 5.4 (matlab 2010a) is too slow comparedto math toolbox 3.1
Dion wrote: I'm making the same observation and find it really, very strange. Especially when the performance gap is so striking. The two versions use completely different symbolic engines. The last few Matlab releases use MuPad for the symbolic engine; the ones before that used Maple. MuPad's language is... 25 May 2010 11:18
