[FF_a(:,j),FF_r(:,j)] = compute_repulsion(P(:,i),Obs(:,j+1),Obs(:,1),Theta(:,i,j+1),Theta(:,i,1),m,po);

这段代码中,`compute_repulsion`函数计算从点`P(:,i)`到障碍物`Obs(:,j+1)`的斥力,其中`Obs(:,1)`是障碍物的中心位置,`Theta(:,i,j+1)`和`Theta(:,i,1)`是机器人当前角度和障碍物中心点的方向角度,`m`是斥力的常数,`po`是机器人半径。`FF_a(:,j)`和`FF_r(:,j)`分别是斥力的两个分量。

这段代码定义了一个类AutocorrelationTest,继承自Test类。它有两个参数:seq_length表示序列的长度,shift表示计算自相关系数时的偏移值,默认为1。在类的构造函数__init__中进行初始化。
