Print figures size and other issues
Hi all, I use Matlab to make a lot of figures for my reports. I'd like to be able to print the figures in a way so that there is a 1:1 ratio between what I display and the saved picture (the -r0 improves the results but I don't get exactly the same results I set using the 'OuterPosition' value). Also I would like to... 14 Jul 2010 12:04

I'm using a MAC with 32GB of RAM and it's still crashing! I was wondering if there was a way to reduce the memory imprint of xcorr? The dataset is a time-series and I'm trying... 16 Jul 2010 19:52
