2d fractional cosine transform

SMOOTH uses a vectorized implementation that may be slow when X and/or FRAME_LENGTH are very large. The number of elements that are used for calculation is length(X)*FRAME_LENGTH. The algorithm vectorizes the operation by creating a matrix of indexes and extracting its diagonals. E.g. for a vector of length 4 and frame_length of 2, the algorithm creates a temporary zero-padded matrix x2 from which it creates a set of indexes:

利用GA來模擬鳥群尋找食物的行為，方法就是找尋距離食物最近的鳥之周圍區域及根據自己本身飛行的經驗判斷食物的所在(The use of GA to simulate the behavior of the flock in search of food, the methodology is to find the nearest bird food from around the region and according to their own experience of flying to judge the location of food)
