蝙蝠算法（BatAlgorithm，缩写BA），是一种元启发式优化算法，是杨新社（音译自：Xin-SheYang）在2010年提出的算法。这个蝙蝠算法以微蝙蝠（microbats）回声定位行为的基础，采用不同的脉冲发射率和响度。(Bat algorithm (BA), a meta-heuristic optimization algorithm, was proposed by Xin-SheYang in 2010. Based on the echolocation behavior of microbats, this bat algorithm uses different pulse emissivity and loudness.)

说明：  《MATLAB数字信号处理85个实用案例精讲:入门到进阶》特点是主要通过案例说明在数字信号处理基础部分编程中常出现的错误和解决方法。《MATLAB数字信号处理85个实用案例精讲:入门到进阶》适用于数字信号处理的初学者，亦可供高年级本科生、研究生和科研工程技术人员参考。("Matlab Digital Signal Processing 85 Practical Cases: Introductory to Advanced" is characterized by cases that illustrate the errors and solutions that often occur in the basic programming of digital signal processing. "Matlab Digital Signal Processing 85 Practical Cases: Introduction to Advanced" is suitable for beginners in digital signal processing, and can also be used as a reference for senior undergraduates, graduate students, and scientific research and engineering technicians.)

电机dqo系统放着程序，大家多交流............(Motor dqo system stood process, everyone was sharing ............)

Addition and multiplication of signals may favour Quality improvement, such as noise reduction, image enhancement, and echo cancellation

求图像的信噪比函数及峰值信噪比函数 很有用(Demand function is useful for image signal to noise ratio)

说明：  用sinc插值和最近领域插值完成距离弯曲校正的完整程序和几篇弯曲校正文章(Using sinc interpolation and nearest domain interpolation to complete the complete program and several bending correction articles)

对一幅图像实现不同角度的旋转，从而可以观察不同角度的结果。( rotate_image- rotates an image given inside a matrix by the amount of "degree" counter-clockwise using linear interpolation of the output grid points from the back-rotated input points in this way, the output image will never have a "blank" point)
