基于有限体积法的naca0012翼型的无粘绕流计算(Calculation of airfoils based on the finite volume method naca0012 inviscid flow around)

这是用于求解精确求解zoeppritz方程的程序，可用于AVO反演，合成地震记录等(This function computes the particle displacement reflection and transmission coefficients (the relative displacement amplitudes) for a solid-solid interface, a liquid-solid interface, a solid-liquid interface, and a liquid-liquid interface. The medium on each side of a given interface is perfectly elastic. The output is the value of the reflection or transmission coefficient, specified by the user at the incidence angle anginc (see input parameters). )

电容层析成像Tikhonov算法的演示实例，带有详细的说明(An example of a demonstration of the Tikhonov algorithm for capacitance tomography, with a detailed description)

电力系统暂态分析中非常有用的三相短路计算程序，只要改变输入就可用于求解具体问题(power system transient analysis is very useful three-phase short-circuit the process. as long as the change in input can be used to solve specific problems)

《电子战信号处理》讲义 ，西电赵国庆老师的经典讲义，学习电子战信号处理的童鞋一定要看看哈(Electronic Warfare Signal Processing)

fftw 快速傅里叶变换， C#算法 直接调用dll(fftw fuliye bianhuan C# suanfa zhijie dianyong dll wenjian zhijie daoru fangzai bin wenjian jia zhong)

说明：  任意给定一个M进制的数X，利用栈实现数值转换。(Given an arbitrary number of M band X, use the stack to achieve numerical conversion.)

说明：  CZT和FFT的C语言实现代码，能有效滤除谐波，噪声。获得信号的频率，是一种良好的频率测量算法。(CZT and FFT of the C language code, can effectively filter out harmonics and noise. Access to the signal frequency, is a good algorithm for frequency measurement.)

说明：  带有不等式/等式约束的加速粒子群算法（apso），主要通过罚函数来进行约束，速度较快，可处理带约束问题(Accelerated particle swarm optimization (APSO) with inequality / equality constraints, which is mainly constrained by penalty function, is fast and can deal with constrained problems)
