  • Ticket #11595 – Description

    v1 v2  
    15157.  One change in behavior - the new `format` command, and its default value of "all".  This will cause eigenspaces of matrices over the rationals formed with algebraic numbers from `QQbar`.  This is consistent with how the `eigenvalues()` method behaves for rational matrices.  When it is not possible to compute eigenvalues this way, the failure is graceful and suggests the `format='galois'` option.  This required just one change outside of the eigen-stuff code (eigenspaces of graphs).  See discussion at:
