      Implementation of FFTW and covariance matrix functionality added · cfea0d77
      Jan Caron authored
      Se_inv: is now handled differently, defaults to eye-matrix, but can be set
              later (added a few convenience functions to DataSet)
      utility: (re-)added utility module for index conversion
      kernel/phasemapper: can now use FFTW library and operate on pre-allocated
              arrays
      dtype: set dtype of arrays to np.float32/np.complex64 (halves memory size),
             also applied to numcore routines!
      magdata: quiver_plot can now plot every n-th arrow (yet untested!)
      reconstruction scripts: modified several reconstruction scripts.

      Big Bunch of small updates! · 4ab7bc63
      Jan Caron authored
      setup: Changes to setup.py, pyramid.version to fit to numpy and jutil
             now uses __all__ magic and supports from pyramid import *
      tests: changes to test_compliance/magcreator/analytic (should now work)
      collaborations: added several scripts for Patrick
      reconstruction: added batch file for the reconstruction of several configs
      test methods: (unfinished) scripts for fftw tests and kernel comparisons
      paper 1: ch5-4 changed padding values to 0, 1, 3 and 7
      plotting: deleted plt.show() lines (have to be done manually now or via Spyder)
      logging: now named _log instead of LOG (private variable instead of constant)
               also some logs were disabled, because Pylint says they are slow...
      reconstruction: now has info argument (pass a list in which cost info is copied)
      phasemapper: changed sign of constant PHI_0, is now correctly positive (instead
                   the negative z-integration is taken into account which was not done
                   before!)
      kernel: now uses FFTW, numpy code was changed accordingly and is still available
      phasemapper: also uses FFTW now, work in progress: FFTW for jac_T_dot

      Intermediat commit on the way to implement norms and more regularizations. · e39061e3
      Jan Caron authored
      minor changes to plotting methods (PhaseMap now plottable without colorbar).
      phase_map: gain can now be set to 'auto' (5 fringes, determined by max. phase).
      renamed 'density' to 'gain' (makes more sense).
      regularisator: started to include norms and more kinds of regularisations.
      mag_slicer: GUI which can go through loaded magnetizations along the major axes.
      paper 1: minor changes to the scripts for the results.

      Quality of life improvements, docstrings, and new gui-based method! · de58b03c
      Jan Caron authored
      Many Doctring corrections, all plots now have a "show" parameter to not show a
      plot at the end of the method (needed for guis and such).
      magdata: quiver_plot: axis switch for x-projection, implemented logarithmic
               arrows and scaling feature.
      projector: added to_mag_data() method to directly produce a projected
                 magnetization distribution.
      gui/create_logo: removed (obsolete and unuseful).
      gui/mag_slicer: added!

                                             phase differences (original - reconstr.)

      Further optimization of the new structure and scripts. · 838fb104
      Jan Caron authored
      package: some minor corrections (mainly import statements), some old functions
               were revived (e.g. in MagData)
      
      scripts: adaption to the new structure and sorting (more work is to do here...)
      
      _version: __version__ string is now imported from this file
      
      phasemapper_core.pyx: added to separate the corresponding numcore_functions
                            from kernel_core.pyx

      Documentation and cleanup of the pyramid package! · 6fc82b2f
      Jan Caron authored
      Renames:
      datacollection --> dataset
      optimizer      --> reconstruction
      
      scripts:
      interactive_setup is now implemented in an extended Spyder startup file.
      some other scripts are now
      the rest is NOT adapted, yet, which is the next task at hand
      furthermore scripts will be sorted and unused ones deleted in the next commit

      Fixed problems with the transposed operations of the forward model which did · a088c4f5

      not represent the correct matrizes (hopefully, now they do).
      
      >>> PACKAGE
      forwardmodel, kernel, phasemapper:
              b_0 is now again inherent part of the kernel.
      projector:
              Corrected .jac_T_dot, now delivers product for the correct matrix.
      >>> SCRIPTS
      simple_reconstruction:
              Does simple compliance tests for 1 and 2 projections and tests a simple
              solver via scipy.sparse.linalg.cg for the reconstruction.
