Test-DiagTensor
|
|
|
|
Description
|
|
Tests for \c DiagTensor constructors, member functions and operators
|
|
using \c floatScalar, \c doubleScalar, and \c complex base types.
|
|
|
|
Cross-checks were obtained from 'NumPy 1.15.1' and 'SciPy 1.1.0' if no
|
|
theoretical cross-check exists (like eigendecomposition relations), and
|
|
were hard-coded for elementwise comparisons.
|
|
|
|
For \c complex base type, the cross-checks do only involve zero imag part.
