Flight Parameters and Quaternion Math

Aerospace parameter calculations and quaternion math

Estimate aerodynamic flight parameters, such as airspeed, incidence and sideslip angles, Mach number, and relative pressure, density, and temperature ratios.

Use built-in quaternion functions to calculate their norm, modulus, natural logarithm, product, division, inverse, power, or exponential. You can also interpolate between two quaternions using the linear, spherical-linear, or normalized-linear methods.Aerospace Toolboxuses quaternions that are defined using the scalar-first convention.
