arcLength

基于matlab的短时傅立叶变换，有语音读取功能！(Based on the short-time Fourier transform matlab, have voice reading!)

这是非均匀B样条曲线构造方法代码，如果有问题可以邮件联系：wuxiaod1987@163.com(NUBUS Spline Build)

三次样条插值（简称Spline插值）是通过一系列形值点的一条光滑曲线，数学上通过求解三弯矩方程组得出曲线函数组的过程。本函数中采用第一类边界值(Cubic spline interpolation (referred Spline interpolation) through a series of key points of a smooth curve, mathematically by solving the three-moment equations derived curve function group process. This function uses the first boundary value)

用C++写的矩阵鞍点求法(C wrote saddle point Matrix Method)

本程序提供大量实用多项式计算函数：求一维实(复)多项式值、求一维多项式组值、求二维实(复)多项式值、两一维多项式相乘、两一维多项式除法、计算连分式函数值。(look it yourself.)

截取地震数据，按道和采样点截取，自动显示截取后的道数和采样点数(failed to translate)

计算多材料单元平均应力应变,用于提取计算等效弹性模量 泊松系数(Calculate the average stress-strain of multi-material elements)

求解无约束优化问题 wolfe线性搜索代码(Wolfe line search for unconstrained optimization)

C写的填充算法源码 算法可是在编程中可是非常重要的 大家可以参考一下这个代码,学习一下算法(C padding algorithm source code algorithm but in programming is very important, you can refer to this code, learn the algorithm)
