- 输入信号y=Acos(2*pi*f*t+c)+B的 A B C 的值, 采样过程中,每两次采样的间隔称为采样周期(Ts)。每次采样所用的时间称为采样时间(τ)。 在程序设计中τ的选择要保证在τ时间内被调量基本保持不变,比较重要的是Ts的选择。-Input signal y = Acos (2* pi* f* t+c)+B the ABC value of the sampling process, the sampling interval is called every two samplin
fitting-of-a-polynomial
- 多项式线性拟合,根据给出的(x,y)值,给出多项式的系数值。-Presented in this paper, according to polynomial linear fitting (x, y) value of polynomial coefficient values.

- 利用SXY文件中的X,Y方向的应力值计算该点的最大主压应力方向。-SXY file use X, Y direction stress calculation of the maximum principal stress direction of the point.
ball_way
- 小球的抛物线轨迹。将轨迹分解成x坐标和y坐标,计算出每一个时刻的x和y值,然后对x和y进行成像就可以得到轨迹了-Parabolic trajectory of the ball. The track is decomposed into x and y coordinates, x and y values calculated each time, then x and y can be imaged on a trajectory
