Ann-rowed correlation matrix may be thought of as an ellipsoid inn-dimensional space with its center at the origin. The principal components of the matrix are essentially the semi-axes of the ellipsoid. A direct and simple method of computing the lengths and directions of these semi-axes is presented.
