Matrix Rotation

  1. Sep 14, 2004 #1
    So here is my question:

    given matrix A = 1 2 3
    2 4 1
    3 1 0

    Does matrix A represent a rotation?

    What I want to know is how do you tell if a matrix is a rotation? Do I simply find the determinant of the matrix? If it is equal to 1, I can say that the matrix represents a rotation right?

    For a matrix to be a rotation, it is also required that the rows/colums of the matrix be orthonormal.
