• Introduce convenience wrappers #70

• Fix #61.
• Minor fixes and doc updates.

Fix a Python 3 issue. Thanks to @zimoun for finding and fixing this!

Fix readthedocs build

Improved README for PyPi.

Drop support for scipy 0.12

Release with usability improvements. Several simplifications were made for an easier use of the functionality in krypy.recycling. No API changes have been made.

This is a feature- and bug fix update:

• new linsys.TimedLinearSystem that times all operations.
• more mature recycling strategies based on timings.
• more efficient computation of residual norms in deflation.bound_pseudo via utils.get_residual_norms.
• bug fixed in deflation.Arnoldifyer.

Now with deflation and recycling support.

Beta release!

• new API
• linear systems are now handled via the linsys.LinearSystem class
• linsys.Minres and linsys.Gmres now use utils.Arnoldi
• new utils.Arnoldi class features several orthogonalization algorithms:
  • modified Gram-Schmidt
  • iterated modified Gram-Schmit
  • Lanczos
  • Householder
• all solvers in linsys can return the corresponding Arnoldi relation
• new submodule deflation enables deflation with all solvers from linsys
• new submodule recycling provides methods for recycling data while solving a sequence of linear systems.
