时间序列预测算法。支持5种常见的算法 移动平均 非线性回归 指数平滑等(ar, ardemo ma)

半导体激光器的数学计算 对速率方程 可能对你计算有点帮助

说明：  用DFT 函数计算电压u, 电流i的基波(f1=50 Hz)的有效值和相位; 用FFT函数分别计算电压u和电流i 所包含的直流,基波和谐波的有效值和初相角; 可计算基波(f1=50 Hz)和各次谐波的功率p和功率因数con?.(The effective value and phase of fundamental wave (f1 = 50 Hz) of voltage U and current I are calculated by DFT function. The effective values and initial phase angles of DC, fundamental and harmonic waves contained in voltage U and current I are calculated by FFT function, respectively. The power P and power factor con of fundamental wave (f1 = 50 Hz) and harmonics can be calculated.)

21位水仙花数的寻找，里面用到了大数乘法等细节上的东西。(find the 21 digits narcissus.)

内插高程点，CASS不提供插求高程点功能，我们手工输入容易出错，且极度不方便，。 此程序用VBA编写，界面操作，按设定的比例自动计算需内插的个数并注记。(Interpolated elevation points)
