MATLAB环境下实现butterworth 低通滤波器仿真(MATLAB butterworth )

用角谱法计算菲涅尔衍射图样，计算出后加上GS算法即可得出全息图(Fresnel diffraction pattern is calculated using the angular spectrum method, after adding GS algorithm to calculate the hologram can be derived)

正交信号校币(OSC)是一种新近发展起来的数据预处理方法，它ff匀基本思 想是仅从光谱矩阵X上移除与相应值矩阵Y正交的部分(Orthogonal signal correction(OSC)is a uew popular pretreatment method，and its basic idea is that it rcn30ves tile pal‘ts linearly unrelated(orthogmml)to the response matrix Y spectral matrix X．)

该文件是一个详细分析PID控制的文件。通过示波器，改变参数下，可以很形象的观察输出波形的变化，这样可以更加直观的学习PID控制，加深对它的理解(The file is a detailed analysis of PID control file. Through the oscilloscope, change the parameters, can be very image of the observed output waveform change, so that we can more intuitive learning PID control, deepen the understanding of it )
