來自matlab 2011b的協助檔案,有時間會翻譯一下。Vectorizing LoopsThe MATLAB software uses a matrix language, which means it is designed for vector and matrix operations. You can often speed up your code by using vectorizing algorithms that take advantage of this

《秘石議會》,書後的封面上面是這樣說的“一本極度緊湊的心理驚悚小說,直叫你頭皮發麻卻又拍案叫絕!“,What can I say?讀的時候一直都有一個感覺,那就是作者是個女的,大概可能是因為主人公是個女的關係吧,於是就有了這樣的錯覺。作者是法國的,讓-克裡斯多夫。格郎熱,男的。與其說這是一部心理驚悚小說,還不如說是一部玄幻偵探小說。個人的感覺是把它作為電影的劇本是不錯,作為小說他的結尾有點太牽強了。如果他純粹是部偵探小說的話,劇情內容,結構都會不錯,但是他加入了‘超能力‘這一元素,結果適得其反,
OverviewStep 1. Compute filter responses to the feature pyramidEach level of features (e.g. 46) is convolved with every stored part filters (e.g. 54), the result subsequently goes to the corresponding filter entry in model.symbols struct. Therefore

最近需要用到ffmpeg,其實一部分也是自己感興趣選了這個試試。目前在windows和mac下都編譯通過,備忘 1. unresolved external symbolimg_convert(AVPicture *dst, int dst_pix_fmt, const AVPicture *src, int pix_fmt, int width, int height); 似乎ffmpeg最近作了些大的介面改動,去年(08年)早些時候把上述函數去掉了,代以swscale,其中有牽涉到GPL,
