I figure gcc 4.0 is doing loop vectorization, so my simple code could be vectorized, but why would it be faster than VML? I've tried building with different architecture and optimizations, but those don't effect the VML timings, which makes sense. I've messed around wit...

테마복사 for : time= 13.5s parfor: time = 5.5s It is OK, but if I create C++ mex (matlab CODER) and run again, the result has changed 테마복사 for : time = 3.1s parfor: time = 4.3s why is the 'parfor' in C++ mex slower than 'for'?댓...
So I made a simple matlab kd-tree implementation of my own and compared it to the matlab function in terms of computation time. It turns out that my own implementation is about 300 times faster? How can this be? Thanks in advance! With kind regards ...
hi, I do image processing in matlab with parallel(parfor) and without parallel and we use tic toc to know elapsed time. Elapsed time for parfor should be faster than without parfor isn't? But my project's results gone opposite. The elapsed time for parallel is hi...
MATLAB is proprietary, closed-source software. For most people, a license to use MATLAB is quite expensive, which means that if you have code in MATLAB, then only people who can afford a license will be able to run it. Plus, users are charged for each additional toolbox they want to ...
why square takes longer than multiplicationMy question is why in matlab square takes more time than multiplication. I read an article, say, square actually can be done a little bit quicker than multiplication. But the test code below doesn't support this. So how does Matlab implement square(...
new class, it has to do extra processing compared to successive loads. On successive loads, all the class information is already cached, so it is much faster. If you put a "clear classes" statement between the two operations, you will find that the ...
Intel is, in particular, great at optimizing modern Fortran code; nevertheless, it offers a plethora of extensions to make code faster should one feel smarter than the compiler.Many thanks to Intel for their Fortran compiler!Jaroslav 0 项奖励 复制链接 回复 所...
