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：  专家pid控制仿真程序，可以共同学习！希望大家多多支持！(Expert pid control simulation program)

C++ code for computation of the inverse matrix with dimension 3x3.

说明：  结合李银斌同学的论文第三章，得到NUFFT算法。zl为非均匀采样值，xl为非均匀网格点，ul为与xl最近的均匀网格点。得到的zk为，均匀频谱(Non-uniform fast Fourier transform)
