说明：  详细描述了通过卡尔曼滤波算法对GSP和imu数据进行融合(merge the gps and imu with the kalman)

FFT，快速傅立叶变换，求一个信号的幅值和相角，频谱特性(FFT, fast Fourier transform, seeking a signal amplitude and phase angle, spectral characteristics)

一种快速富式变换源程序,对于数字信号处理非常有用。(a usefull FFT code is very convenient to signal process )

FFT快速傅立叶变换，DSP实际例子，学习的一手好资料。放进CCS仿真(FFT Fast Fourier transform, DSP practical examples)

一维CSAMT正演程序，对学地球物理的有帮助(CSAMT)

工具箱 (粗糙集数据分析工具箱) matla 中使用 (Kit (Rough Set Data Analysis Toolbox))

分数阶滑模工具箱，可用于解决阶次比较低的时候(fractional order sliding mode )

这是大地电磁一维正演程序，只要输入电阻率和深度即可正演计算；使用的是卡尼亚视电阻率公式，有关说明已经在文件中说明。(This is a one-dimensional magnetotelluric forward the program, as long as the input resistivity and depth to forward calculation use Carney ATV resistivity formula, and instructions in the file description.)

复合材料破坏失效vumat子程序，使用hsshin准则判断失效，具有刚度缩减，(The VUMAT subroutine for failure of composite materials is judged by hsshin criterion, and stiffness is reduced.)

说明：  自己编写的期望最大化（EM）算法的MATLAB实现，里面有较为运行方法和程序说明，对新手有很好的帮助( I have written the expectation-maximization (EM) algorithm in MATLAB, which has run more methods and procedures described, there is a good help for the novice)
