一本matlab rune教材，有很多实例，比较简单，学习过程中可以不断尝试。(A book about matlab,it can be used by those who knows little about matlab.)

此程序实现图象增强的功能，采用直方图均衡化的方法来实现图像增强。(This procedure realize the function of image enhancement using histogram equalization method to achieve image enhancement.)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading
