Large Arrays - Memory Problems
Dear All, I'm running into serious memory problems with Matlab 2010a and large arrays. I have 32bit WinXP and have tweaked all the memory options as much as I can. My data sets are quite big and thus I'm running into memory problems still. In particular I have an 4d double array which I'd like to have as (230,130... 29 Apr 2010 08:58

I keep getting error using plot messgaes and can't see any errors....
Please could someone have a look at the code and assure me im not being an idiot. I have heard that i may be missing a module on matlab but can't see how to check. f = [0.5 1 2 5 7 10 15 20 30 50 100]'; w = 2*pi*f; a = [-1 -1 -1 -1 -1 -0.9 -0.9 -0.45 0.3 0.1 0]'; b = [0 0 0.05 0.25 0.4 0.7 0.7 1 0.4 0.05 0]'; %%... 29 Apr 2010 10:06

dynamically scaling transfer function coefficients
Hi Denis, This isn't a dumb question, it is a toal pain that you cant manipulate the Numerator & Denominator in a Transfer Function Block. I had the same problem and posted a message on here (subject: "Making A Transfer Function Denominator Variable With Time") but no one could help me out. I took it as if what ... 29 Apr 2010 07:51

Making A Transfer Function Denominator Variable With Time
No problems, I have given up. I assume that the complete lack of response means that the problem I described is not 'fixable'. I reverted to the much more complicated approach of: So, basically all Transfer Functions can be built using an Integrator (1/sTn) and +,-,* & / blocks. If you arrange the blocks correc... 29 Apr 2010 07:51

error : ??? Subscript indices must either be real positive integers or logicals.
I have written a function that calculates some variable "t": function t=t_from_phi(phi, far) i = 0; t = exp((phi - 2.81661)/3.648659); error = phi - phi(t, far); while (abs(error) < 1e-06) || (i > 30) i = i + 1; error = phi - phi(t, far); if(abs( error1) > 1e-06); error2 = phi - phi((t+5)... 29 Apr 2010 07:51

Figure popunder?
Hi, I've got Matlab plotting out a few hundred images and writing each of them to png files in a for loop. I'd like to keep working on my pc, doing other things while Matlab writes out the pngs quietly in the background, however everytime the loop encounters the 'figure' command, the figure pops up right in front... 29 Apr 2010 08:58
