MATLAB

基于改进的广义S变换，能更好的对数据进行时频分析。(Modified S-transform and its application in data analysis)

FFT和FIR 快速傅里叶变换和FIR滤波器实验程序(Fast Fourier Transform FFT and FIR and FIR filter experimental procedure)

说明：  二阶曲线拟合，最小二乘法，此程序是在c++ builder6.0环境下开发的(second curve fitting, least squares method, this procedure is in c builder6.0 development of the environment)

数据归一化处理，对数据进行一个标准化处理，将各个不同单位的变量，转换成无量纲的量(Data normalization, a standardization of data processing, will be different units of variables, into dimensionless quantities)

使用惩罚函数法对机械设计中的问题进行优化处理(The use of penalty function method for mechanical design optimization problems deal with)

说明：  c++编程bp神经网络，用c++语言编写的bp神经网络(C++ programming bp neural network, bp neural network written in c++ language.)

一个有限元计算的例子,初学者可以参考，简单易看懂(an example of FEm computation)

主要用于三次样条拟合，对离散点进行拟合插值，(Three order spline fitting)

线弹性模型，可以对一般的弹性体通过abaqus进行验证使用(Linear elastic model)

快速傅立叶变换的程序，附有试验用数据，希望对大家有所帮助(Fast Fourier Transform procedure, with test data, and they hope to help everyone)
