PSI

The PSI function expression calculates the first angle (in radians) of a body-fixed 3-1-3 Euler rotation sequence between markers i and j. Marker j defaults to the global coordinate system if it is not specified. For a schematic of the body-fixed-3-1-3 Euler angles, click here.

Format

PSI(i[,j])

Arguments

 
i
The marker whose rotations are being sought.
j
The marker with respect to which the rotations are being measured.

Examples

REQUEST/1, F2=PSI(222,434)
This REQUEST statement output the psi angle between Markers 222 and 434 in its second column.
