The interim scientific report comprises a description of a number of usable computer subroutines developed under the research program. These subroutines concern themselves with manipulations with matrices. The main subroutines developed are NEIGEN computes all eigenvalues and eigenvectors of a complex matrix with a high degree of precision. ONEIG computes one eigenvalue and one unit vector, namely the first column of a unitary matrix of a complex matrix. SEIGEN computes the eigenvalues of a real symmetric matrix as well as the eigenvectors and sharp bounds for the relative errors. Author
