It is the whole purpose of a rotation matrix!

An ordinary matrix by vector product is applied. [/size][/font][font="arial, verdana, tahoma, sans-serif"][size="2"]Look e.g. at [url="http://www.euclideanspace.com/maths/algebra/matrix/orthogonal/rotation/index.htm"]Euclidean Space on rotation matrices[/url]. And e.g. at [url="http://en.wikipedia.org/wiki/Matrix_multiplication#Non-technical_example"]wikipedia on the matrix vector product "non-technical example"[/url] (remember that a vector is a matrix with either 1 column (a so-called column-vector) or else a matrix with 1 row (a so-called row-vector), so a matrix by vector product is just a special case of a matrix by matrix product).[/size][/font]
