SFLOP simulates a floating point operation x op y where op = +, -, *, / In chopping or rounding arithmetic using an m digit mantissa, base 10, and an unrestricted exponent range. (sflop: Simulate FLOating Point operation.) For more details on the how the floating point representation of a number is computed see the function sfl.( SFLOP simulates a floating point operation x op y where op =+,-,*,/ In chopping or rounding arithmetic using an m digit mantissa, base 10, and an unrestricted exponent range.

计算冲击电压波下的Q-V图,雷电波或操作冲击波均可(simulation of q-v curv under thounder)

说明：  VC与MATLAB混合编程，示范例子 使用C++开发(VC versus MATLAB )

Gps Indicator extends Basic Indicator Source Code for Andriod.

判断半正定矩阵与正定矩阵间的一种新的准则，gky方法是判定系统是否稳定的一种很有效的方法，里面有源代码和相应文档(Judge half positive definite matrix and the positive definite matrix, a new criterion between gky method is to determine whether the system stability of a kind of very effective method, there are source code and documentation accordingly)

SIFT特征点检测，配准、匹配，代码经验证可用(sift match ransac appendimages)

说明：  LMD，局部均值分解算法，主要用于对振动信号进行分析，不需要设置分解参数(LMD, a local mean decomposition algorithm, is mainly used to analyze vibration signals without setting decomposition parameters.)
