 Items(21) /3 Next >> Last >| vectorization question #5 3 17 (4/18/2008 2:23:50 AM) comp.soft-sys.matlabHi all, how do I vectorize the following? for r = 1:rows for c = 1:cols A(Y(r,c),X(r,c)) = A(Y(r,c),X(r,c)) + 1; B(Y(r,c),X(r,c)) = B(Y(r,c),X(r,c)) + C(r,c); end end Here X and Y are ...RS vectorization question #4 2 16 (3/18/2008 3:33:11 AM) comp.soft-sys.matlabHi all, I am relatively new to matlab and want to vectorize something, as an example, like x=[1;4;8;17]; y=zeros(4,3); for k=1:4 y(k,:)=x(k):x(k)+2; end Obviously the following won't work x=...RS CD won't eject 7 34 (3/9/2008 4:49:42 PM) comp.sys.mac.miscHi all, I have apparently a bad CD in the CD drive on my iMac Leopard (intel) machine. Nothing in it was recognized and now it won't eject. I have tried to eject it and it just sits there. The trash icon loo...RS OSX Leopard: Firewall in stealth mode 2 40 (2/25/2008 3:57:10 AM) comp.sys.mac.miscHi all, Could someone please tell me what are the pros and cons of turning the Stealth Mode on for the OS X Leopard software firewall? Is there any reason why it should not be on by default for a home desktop ...RS Need advice from Verizon FIOS users 11 32 (2/25/2008 3:54:48 AM) comp.sys.mac.miscHi all, I am looking to replace my current ISP with Verizon FIOS, but I can't seem to get pre-order technical support from them. So I am looking for OS X (Leopard) users that are FIOS customers. There are a fe...RS Robust fitting of curves and surfaces in 3D 0 12 (6/25/2007 12:59:18 PM) comp.soft-sys.matlabHi all, Is there a routine that can fit curves and surfaces (or at least lines and planes) to 3D data that has outliers? Thanks, RS ...RS Robust fitting of planes for 3d data with outliers 0 15 (6/23/2007 2:02:56 PM) comp.soft-sys.matlabHi all, is there an available routine that can do robust fitting of 3d points to planes and lines in space (or more general surfaces or functions) when there are outliers? Thanks, RS ...RS Optimization with fminsearch 1 15 (6/21/2007 1:13:07 PM) comp.soft-sys.matlabHi all, I just inherited a code that uses fminsearch to minimize a function of 12 variables. Does anyone know if fminsearch is capable of accurately optimizing such large number of variables? Speed is of sec...RS making a n-dimensional array out of n vectors 2 15 (5/19/2007 2:25:06 AM) comp.soft-sys.matlabHi all, This is probably a trivial question: What is the most efficient way to make an n dimensional array out of n vectors (of lengths k1, k2, ..., kn) in such a way that the array has n columns, and k1 x k...RS int versus unsigned int - optimizing for speed 4 13 (12/12/2006 3:12:29 AM) comp.lang.c++Hi all, I was told that using unsigned int instead of int can speed up the code. Is this true? If so, why? Are there are any other rules one should follow to optimize the code for speed (i.e. using float in...RS

They have disappeare... DLLs in matlab 4 25 (9/23/2006 1:03:28 AM) comp.soft-sys.matlabHi all, I have made a DLL using visual C++ and calling it in matlab using the calllib function. The functions in the DLL have a lot of print statements (std::cout) for diagnostic purposes. However they don't... Maximum 2D Filter in C++ 3 15 (10/20/2006 4:25:20 AM) comp.dspHi all, I am looking for an efficient implementation of the 2D maximum filter in C++. I tried to write one using the Blitz library, but my code's speed is far slower than the matlab code. I am new to the fie...
