alphabeta

Compute incidence and sideslip angles

Syntax

[incidence sideslip] = alphabeta(velocities)

Description

[incidence sideslip] = alphabeta(velocities) computes m incidence and sideslip angles, incidence and sideslip , between the velocity vector, velocities, and the body.

Examples

Determine Incidence and Sideslip Angles for Velocity for One Array

Determine the incidence and sideslip angles for velocity for one array.

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

alpha = 0.1194

beta = 0.3780

Determine Incidence and Sideslip Angles for Velocity for Two Arrays

This example shows how to determine the incidence and sideslip angles for velocity for two arrays.

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

alpha = 2×1

    0.1194
    0.3805

beta = 2×1

    0.3780
    0.0926
