Optimising generated video processing code running on a Ti DM6437
I've made a Simulink model to do image segmentation on a TI DM6437EVM (davinci processor evaluation board). My algorithm uses only the luminance values and since the format of the input image is UYVY (i.e. 4:2:2 YCbCr) I'm doing some processing at either end to convert to and from an array of Y's. When it comes to disp... 18 Jun 2010 14:38

How does MATLAB exploit matrix multiplication's associativity?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, How does MATLAB exploit matrix multiplication's associativity? Given A B C such that their product is possible (in matrix terms), it often happens that complexity(A(BC)) != complexity((AB)C). So, how does MATLAB guess this? Is there a well-known algorithm a... 29 Jun 2010 16:17

circumstantial?
Hi guys. I currently have a plotting function, trail5(m,n,o) where I want to make sure that at any time m+n+o=integer. I also want to make trail5(m,n,o)=plot with values of 1 through d in stems of 1/2, 1 through g in stems of 1/2, 1 through h in stems of 1/2, in order to make many copies of my image. (I input d,g,h ... 18 Jun 2010 21:16
