Quaternion Math

Aerospace quaternion math

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 Toolbox uses quaternions that are defined using the scalar-first convention.
