Hello, first time question asker here.
I am trying to orient a smartphone whlist it is in a persons pocket. I collected accelerometer, gyroscope, and magnetometer data from the phone. Next i used the ahrsfilter to output quaternions relative to the NED reference frame.
Next i created a rotation matrix using rotationMatrix = quat2rotm(orientation). this gave me my rotation matrix.
Now here is the problem. My acceleration data which i want to rotate is in a 940x3 (X Y Z) array and my rotation matrix is in a 3x3x940 multidimensional array. So, how can i multiply each of my acceleration points with the appropriate rotation matrix. I suspect i will have to use a loop, however i am unsure about how to do this. How would you go about doing this?
