Calculate spacing for helix with pitch varying from 12 degrees to 14 degrees in steps of 0.5 and 20 mm radius.
s = helixpitch2spacing(12:0.5:14,20e-3)
s = 1×5 0.0267 0.0279 0.0290 0.0302 0.0313
Calculate spacing for helix with pitch varying from 12 degrees to 14 degrees in steps of 0.5 and radius 20 mm.
Calculate the spacing of a helix that has a pitch of 12 degrees and a radius that varies from 20 mm to 22 mm in steps of 0.5 mm.
s = helixpitch2spacing(12,20e-3:0.5e-3:22e-3)
s = 1×5 0.0267 0.0274 0.0280 0.0287 0.0294
Calculate spacing for helix with pitch varying from 12 degrees to 14 degrees in steps of 0.5 and radius varying from 20mm to 22mm in steps of 0.5.
s = helixpitch2spacing(12:0.5:14,20e-3:0.5e-3:22e-3)
s = 1×5 0.0267 0.0286 0.0305 0.0324 0.0345
Pitch angle of helix, specified as a scalar or vector in meters.
Example: 12:0.5:14
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.
Spacing between helix turns, returned as a scalar or vector in meters.
