alphabeta - Compute incidence and sideslip angles

Syntax

[a b] = alphabeta(v)

Description

[a b] = alphabeta(v) computes m incidence and sideslip angles, a and b, between the velocity vector and the body. v is an m-by-3 array of velocities in body-axes. a and b are in radians.

Examples

Determine the incidence and sideslip angles for velocity in feet per second:

[alpha beta] = alphabeta([84.3905  33.7562  10.1269])

alpha =

    0.1194


beta =

    0.3780

Determine the incidence and sideslip angles for velocity in knots:

[alpha beta] = alphabeta([50 20 6; 5 0.5 2])

alpha =

    0.1194
    0.3805


beta =

    0.3780
    0.0926
