LSM9DS1 A 9 degree of freedom Inertial Navigation Chip

Now working for all 8 quadrants.
On to doing the rotations for the magnetometer vector to do final proof of concept.
Then to see if pre-multiplying the matrices (using Maxima) and using simpler code will work.
Finally how well will it work with data from the chip?
Didn't use atan2. used the abs(atan) and then the sign of the original x,y values to set the matrix rotation direction and the z value to control if the final matrix is needed.
