PID仿真程序，只需要人工修改PID参数，及根据自身情况修改模型参数就可以轻松实现PID仿真。(PID code in matlab)

可以实现十进制转换成任意字长的二进制。并又可以按照这个二进制转换成十进制。这个程序对于分析不同字长对于IIR数字滤波器和FIR滤波器的影响是非常有用的。(Decimal to convert any word length of the binary. And also in accordance with this binary to decimal conversion. This program is very useful for the analysis of the impact of different word length for the IIR digital filter and FIR filter.)

This Algorithm comutes demagnetizig tensor from Newell Paper[1] between two rectangular shape elements.Main function is and there is equivallent function written in c-language, you can use it to compile mex file.This script can be used in field of micromagnetics and finite difference magnetic simulation software. 1.
