说明：  实现信号的frft变换,傅立叶变换是将观看角度从时域转变到频域，分数阶傅立叶变换就是以观看时频面的角度去旋转时频面的坐标轴，然后再从观察频域的角度去分析信息。(The FRFT transform of signal is realized)

50－channel的polyphase filter，基于FIR滤波器(50-channel of the polyphase filter, based on the FIR filter)

在MATLAB平台上编写的遗传算法GA程序(GA program using matlab)

用于计算电力系统的节点阻抗或者导纳，还算比较好用。(It can be used to calculate nodal impedance or admittance of power system.)

介绍了基于MATLAB和excel的数值分析数值分析方法，(Introduced based on MATLAB and excel in the numerical analysis numerical analysis,)

说明：  数值随机化算法计算圆周率，面积法投点计算，利用matlab，绘出不同投点下的计算结果(Randomized algorithm to calculate the value of pi, cast-point calculation of area method, using matlab, plot points under different investment results)

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.)
