This function convert a speed vector represented in complex number into a bearing angle (0°=N ;
90°=E...). This conversion is needed because trigonometric angle are different than bearing.
Usage
speed2bearing(
speed,
speed_ref = complex(real = 0, imaginary = 1),
positive = TRUE
)
Arguments
- speed
speed as complex value
- speed_ref
reference vector of the angle. Default is the North in order to return bearing.
Use speed_ref = 1 for trigonometric orientation (clockwise from East).
- positive
logical to ensure the bearing is positive between 0-360 degree.
Value
bearing angle in degree
