用于读取mit心电数据库程序，运行环境matlab，对研究心电非常有用！(Mit to read ECG database program, runtime environment matlab, the study ECG is very useful!)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

说明：  MATLAb用法函数介绍,及其用法，还有比较(Matlab some hanshu for program only)

Many source code for bootstrap technics developped in matlab are presented in attached files.

此函数专为求解球贝塞尔函数 利用柱贝塞尔函数与球贝塞尔函数之间的关系得到 十分实用 (This function is designed to solve the spherical Bessel functions to take advantage of the relationship between the column Bessel functions and spherical Bessel functions very useful)

距离保护simulink程序，可实现相间短路和接地短路。(Distance protection simulink program.the distance protection of phase faults and earth faults can be realized.)
