{title:Description}

{pstd}
Given an n by n nonsymmetric (real) matrix {it:A}, {cmd:matrix eigenvalues}
returns the real part of the eigenvalues in the 1 by n row vector {it:r} and
the imaginary part of the eigenvalues in the 1 by n row vector {it:c}.

{pstd}
If you want the eigenvalues for a symmetric matrix, see 
{helpb matrix symeigen}.
