Input Arguments
a
— Pitch angle of helix
scalar in meters | vector in meters
Pitch angle of helix, specified as a scalar or vector in meters.
Example: 12:0.5:14
r
— Radius of helix
scalar in meters | vector in meters
Radius of helix, specified as a scalar or vector in meters.
Example: 20e-3
Note
If the pitch angle and radius are both vectors, then their lengths must be equal.
Output Arguments
s
— Spacing between helix turns
scalar in meters | vector in meters
Spacing between helix turns, returned as a scalar or vector in meters.
