postmultiply method
Transforms this into the product of this as a row vector,
postmultiplied by matrix, arg.
If arg is a rotation matrix, this is a computational shortcut for applying,
the inverse of the transformation.
Implementation
void postmultiply(Matrix3 arg) {
final Float64List argStorage = arg.storage;
final double v0 = _v3storage[0];
final double v1 = _v3storage[1];
final double v2 = _v3storage[2];
_v3storage[0] =
v0 * argStorage[0] + v1 * argStorage[1] + v2 * argStorage[2];
_v3storage[1] =
v0 * argStorage[3] + v1 * argStorage[4] + v2 * argStorage[5];
_v3storage[2] =
v0 * argStorage[6] + v1 * argStorage[7] + v2 * argStorage[8];
}
