说明：  IMU 计算器 能够计算IMU的三轴陀螺仪的飘移，三轴加速度计的偏移，俯仰、横滚、偏航角度，三轴位置信息。画出上七个数据的图像。
(This function takes the IMU data as the input and returns the plot of x,y,z,theta,phi,psi,u,v,w. %The data is a 7 coloumn matrix with each row representing a reading of the %IMU. %the coloumn should contain the data in the following format: %col data %1 time %2 Ax %3 Ay %4 Az %5 p(angular rate along x) %6 q(angular rate along y) %7 r(angular rate along z) % Initial is a 3x3 matrix containing initial position and attitude % [phi theta psi % u v w % x y z])
