qc_open_library('quarc_library/Math Operations/Matrices')Description
This block converts a rotation matrix to the equivalent rotation angle about a fixed axis. If the rotation matrix represents a rotation of zero radians then the z-axis is returned with a rotation angle of zero.
Input Ports
R
The 3x3 rotation matrix to convert to an angle and axis.
Output Ports
theta
The angle in radians through which to rotate about the axis.
k
The axis about which to rotate as a 3-vector.
Parameters and Dialog Box
The Angle and Axis from Rotation Matrix block has no parameters.
