So I'll be hoping to take a eal matrix and use lapack to give me the Hessenberg form, which, I can then use for bigger and better things. Hi, Lapack has both...
...for the eigenvalues and eigenvectors of a real or a real symmetric matrix. So when I want to calculate, say, the eigenvectors of a real matrix A I type v=eigVectors(A), or if I want the eigenvectors of a symmetric matrix A I type v=eigVectors(A,sym="Y"). In this way ... cumbersome argument list of the LAPACK routines does not appear, or have to be used anywhere. Michael
