说明：  音频编解码，语音信号处理，乘法次数最少，可嵌入编码器(Audio codec, speech signal processing, the least number of multiplication can be embedded in the encoder)

cordic algorithm is very use ful for implemention sin and cos and trangulation function

从Excel表中读取数据，然后分析其频谱、相谱和总谐波畸变率，并画出图（plot）。(Read data from an Excel table, and then analyze its spectrum, phase spectrum and total harmonic distortion rate, and draw the diagram (plot).)

曲线拟合的MATLAB代码程序。包括高期拟合等。(fitting)

本书简绍了matlab编写有限元程序的整个流程(The goal of this document is to give a very brief overview and direction in the writing of nite element code using Matlab. It is assumed that the reader has a basic familiarity with the theory of the nite element method, and our attention will be mostly on the implementation. An example nite element code for analyzing static linear elastic problems written in Matlab is presented to illustrate how to program the nite element method.)

说明：  此程序包含了相空间重构的延迟时间、嵌入维数的计算(This program includes the delay time of phase space reconstruction and the calculation of embedded dimension)

说明：  Bit error probability curve for BPSK with channal for wimax

Some algorithms in the realm of ultrasound

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.

Given a point, it finds whether the point is inside or outside of the polygon, given polygon vertices.
