computeMoonFixedToIcrfMatrix
fun computeMoonFixedToIcrfMatrix(date: JulianDate, result: Matrix3? = definedExternally): Matrix3(source)
Computes a rotation matrix to transform a point or vector from the Moon-Fixed frame axes to the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes at a given time.
// Transform a point from the Fixed axes to the ICRF axes.
const now = JulianDate.now();
const pointInFixed = Cartesian3.fromDegrees(0.0, 0.0);
const fixedToIcrf = Transforms.computeMoonFixedToIcrfMatrix(now);
let pointInInertial = new Cartesian3();
if (defined(fixedToIcrf)) {
pointInInertial = Matrix3.multiplyByVector(fixedToIcrf, pointInFixed, pointInInertial);

Return
The rotation matrix.
Parameters
date
The time at which to compute the rotation matrix.
result
The object onto which to store the result. If this parameter is not specified, a new instance is created and returned.
