Stop windows sleeping while matlab running
Hello, So this should be pretty simple but I can't figure out how. I'm running a set of data analysis functions (basically a lot of parfor loops) that take about four hours to finish. Unfortunately during that time windows goes to sleep and the whole thing breaks. I don't really want to turn of sleep in Windows as I... 28 Apr 2010 18:35

Tridiagonal matrix - repeated solution
Hello, my problem involves solving a system of equations Ax=b for different RHS vectors b. A is tridiagonal / complex / sparse. I can obviously repeatedly use x = A\b, however, this does not seem to be very fast. I know that Matlab can solve this problem very efficiently if I put all vectors b in a matrix, let's ... 31 Mar 2010 17:42
