　数字水印技术是近年来图像保护技术研究领域的一个热点,本文提出了一种基于小波变换的图像数字 水印嵌入算法的Matlab 实现。实验结果表明,该算法具有较好的视觉效果和透明性。(　Abstract 　The digital watermarking technology is the most active topic in image protecting recently. In this paper , a digital watermarking algorithm based on Wavelet transform is proposed ,and give ou the program of this algorithm by MatLab. The experimental results demonstrate that the method possess good vision effect and transparence.)

此程序实现sinc函数的绘制，在自适应波束形成里可以视为波束图(This process of mapping implementation sinc function in adaptive beamforming can be regarded as a beam map)
