用窗函数法设计一个长度N等于8的线性相位FIR滤波器。其理想的幅频特性为 分别用矩形窗、Hanning窗、Hamming窗、Blackman窗、Kaiser窗(ｂ=8.5)设计该滤波器。 (Window function method used to design a length N equal to 8 the linear phase FIR filter. Its ideal amplitude-frequency characteristics of rectangular windows, respectively, Hanning window, Hamming window, Blackman window, Kaiser window (b = 8.5) the design of the filter.)

说明：  用简正波方法进行声场计算的karaken程序(karaken program for acoustic field caculation by nomal mode method)

实际光源不是绝对的单色，包含一定的光谱宽度△λ。△λ范围内的每一种波长的光都生成各自一组干涉条纹，除零干涉级外，相互间均有位移，使条纹对比度下降。(The actual light source is not absolutely monochromatic, contain a certain spectral width △ λ. Each wavelength of light within the range △ λ generates a set of interference fringes each, in addition to the zero level outside interference, mutual displacement are so fringe contrast decreases.)

火焰检测的matlab实现方法里面有实现特征提取语句(Flame detection)

使用MATLAB写的计算器，可以随意添加、删除数据。(Simple Calculator , with funny tweaks Feel free to Add/delete anything)

用于计算超长程表面等离子体共振角度谱的反射率曲线(super long-range surface plasmon resonance is used to calculate the spectral reflectance curves of the angle)

matlab 中使用srm实现图像分割的源代码， 包里包括srm.demo和实验图像还有源代码(srm used matlab image segmentation source code package includes srm.demo and experimental images as well as the source code)

说明：  Gerchberg–Saxton（GS）算法是一种迭代算法，用于检索通过传播函数（如傅里叶变换）相关的一对光分布（或任何其他数学上有效的分布）的相位，前提是它们在各自光学平面上的强度已知。(The algorithm is an iterative algorithm for retrieving the phase of a pair of light distributions.)
