图像的方向图处理，通过各类算法实现方向图的获取。(The direction of image processing, algorithm through various access patterns.)

说明：  一楼房的后面是一个很大的花园. 在花园中紧靠着楼房有一个温室,温室伸入花园2m,高3m,温室正上方是楼房的窗台. 清洁工打扫窗台周围,他得用梯子越过温室,一头放在花园中,一头靠在楼房的墙上. 因为温室是不能承受梯子压力的,所以梯子太短是不行的. 现清洁工只有一架7m长的梯子, 你认为它能达到要求吗? 能满足要求的梯子的最小长度为多少?(The back of a building is a big garden. In the garden close to a building in a greenhouse, greenhouse into the garden 2m, high-3m, the greenhouse is the top of the building' s bay windows. Cleaners cleaning around the windowsill, he crossed to use a ladder greenhouse, on a garden, against a building wall. because of the greenhouse can not bear the pressure of a ladder, so the ladder is not too short. cleaners are only a 7m long ladder, do you think it can meet the requirement it? ladder to meet the requirements of the minimum length of the number?)

introduction for plotting graphs in matlab

frequency expander. Matlab code for expander.When x is a vector, this function adds L-1 after each element of x. When x is a matrix, each column of it treated as vector and expanded L fold. SQUARE-ROOT RAISED-COSINE PULSE: h=sr_cos_p(N,L,alpha) This function generates a square-root raised-cosine pulse of length N+1. There are L samples per symbol period. alpha is the roll-off factor.
