fmincon optimization
Hi, In my fmincon optimization of 2 control variables and 3 state variables I would like to keep one of the optimized control variables fixed for several loops, while the other control variable is still optimized in each loop. To be more specific, say the control vars are A and B and the state vars are x,y,z. Then:... 7 Jun 2010 23:16

Computation time reduction between using "parfor" and "for" loops
Hi, I have just bought Matlab Parallel Computing Toolbox and tried to use some very simple test to see how much time I may be able to save by using "parfor" instead of "for" loop. I have 4 processors on my local PC and I used matlabpool to open them all. To my surprise, using "parfor" is not too much faster than using ... 8 Jun 2010 11:25

Plotting Line Iteratively
Hi, I would like, in a loop, to plot a dynamic line. What I'm looking for it the line start at zero, then a random point is generated and the line goes to that point (1,randompoint1) then a pause, then it extends to (2,randompoint2) etc.. This should continue until the loops stops. It should be an easy task but I c... 7 Jun 2010 19:57
