Simulink Simulation Duration
I am simulating a spacecraft timekeeping system using Simulink. The system runs off of a 1 MHz clock. Accordingly, the simulation progresses with a step size of (10^-6)/2. I found that it takes roughly two minutes of real world time to simulate 1 second of spacecraft time. Is there any way to optimize or speed up t... 1 Mar 2010 12:31

xlswrite Errors - Not enough storage to complete the operation
Hi, I'm using XLSWRITE to write an matlab array to Excel files. The Matlab arrays are usually around 65 MB and after I've completed 6 such array writes, xlswrite fails with the error "Not enough storage to complete the operation". I looked up the memory available to MATLAB and it seems to have enough memory for MAT... 1 Mar 2010 16:26

why does Matlab fail to release memory even if I clear all the variables?
The program occupies increasing memory storage and the computer becomes slower and slower... finally, the error of "out of memory" happens. However, during the running of the program, no new variable is created. Why does the program needs an increasing memory? Possibly, I think, this may be caused during calling 'm... 1 Mar 2010 09:09

Multithreaded and PCT sparse matrix inversions?
Since this topic will concern my work for the next year or so (and for many other people I'm sure), I'm just wondering if there's a timeline at the Mathworks for the implementation of these two (related but definitely not the same) functions? Specifically: 1) Multithreaded sparse inversion (slash, not LU or QR or et... 1 Mar 2010 11:22
