VectorAngle_x
The VectorAngle_x function requires 1 parameter, which is the name of a vector. This function must be placed after the $Vector (or $Vector2D) directive that identifies a vector variable.
The function returns the angle between the positive x-direction and the vector. The angle is returned in units of degrees or radians, depending on the setting of the unit system for angles. See $UnitSystem.
Example:
$Vector V
$UnitSystem deg
V=VectorAssign(1,2,3) [N]
a_x=vectorangle_x(V)
{Solution:
a_x=74.5 [deg]}
