multiplyTransformation

Computes the product of two matrices assuming the matrices are affine transformation matrices, where the upper left 3x3 elements are any matrix, and the upper three elements in the fourth column are the translation. The bottom row is assumed to be 0, 0, 0, 1. The matrix is not verified to be in the proper form. This method is faster than computing the product for general 4x4 matrices using Matrix4.multiply.

const m1 = new Matrix4(1.0, 6.0, 7.0, 0.0, 2.0, 5.0, 8.0, 0.0, 3.0, 4.0, 9.0, 0.0, 0.0, 0.0, 0.0, 1.0);
const m2 = Transforms.eastNorthUpToFixedFrame(new Cartesian3(1.0, 1.0, 1.0));
const m3 = Matrix4.multiplyTransformation(m1, m2, new Matrix4());
