matlab中find函数的作用，其实，能看MATLAB的帮助文档，就能够知道大概的意思了(find function in matlab)

直线阵自然指向性仿真,先根据设定的角频率仿真单频信号A sin(ωt)；再根据阵元间距、入射角度计算得各阵元相对参考阵元接收的信号的时延 τ (dsin(θ))/c。 假设等间隔N基元线阵，入射信号是平面波，那么阵元输出信号为：S_n (t) A sin(ωt+nφ)；其中 φ 2πfτ 为相邻阵元接收信号间的相位差；再将基阵各元输出求和，取最大值max,就得到输出幅度；以入射角为横坐标，幅度为纵坐标作图得直线阵自然指向性。 (Linear array directivity simulation)
