save_eigenspectrum Interface

public interface save_eigenspectrum

Description

Utility function to save the eigenspectrum computed from the Arnoldi factorization. It outpost a .npy file.

Syntax

    call save_eigenspectrum(eigvals, residuals, fname)

Arguments

  • eigvals : complex rank-1 array containing the eigenvalues. It is an intent(in) argument.

  • residuals : real rank-1 array containing the residuals associated to each eigenvalues. It is an intent(in) argument.

fname : Name of the file to save the eigenspectrum. It is an intent(in) argument.


Subroutines

private module subroutine save_eigenspectrum_cdp(lambda, residuals, fname)

Saves the eigenspectrum and corresponding residuals to disk use the npy binary format.

Arguments

Type IntentOptional Attributes Name
