Some of the difficulties encountered in the problem of obtaining the elgenvalues and eigenvectors of a matrix appear to be due to the fact tha t its eigenvalues are small compared to its norm.â€¦ (More)

I t is well known [5] that the conditioning of A*A is worse than that of A. This frequently leads to difficulties which cannot be remedied by the application of conditioning processes to the matrixâ€¦ (More)

This talk concerns a method for solving the set of simultaneous linear equations (A âˆ’ Î±I)x &equil; b, in which the n x n matrix A, the scaler Î±, the vector b and the unknown vector x can either beâ€¦ (More)

That which follows is concerned with improving the condition of a matrix for the purpose of obtaining its eigenvalues and eigenvectorsÂ° Some of the difficulties encountered in the eigenvalue problemâ€¦ (More)
