Package settings
========================================

You can set the following global variables to the desired value at any point in your code using

.. code-block:: python

	grassmanntn.<variable name> = <value>

.. list-table::
   :align: left
   :widths: 10 5 20
   :header-rows: 1

   * - Global variable
     - Default value
     - Description
   * - grassmanntn.progress_bar_enabled
     - `False`
     - If `True`, show the progressbar in various processes.
   * - grassmanntn.numer_cutoff
     - 1.0e-14
     - To avoid fatal errors, numbers with norm less than this parameter are counted as zero. This parameter is also used in the method ``.remove_zeros()``
   * - grassmanntn.numer_display_cutoff
     - 1.0e-11
     - This is used in two contexts. 1) Counting nonzero elements of a tensor (in ``.nnz`` attribute) and 2) Number with norm less than this parameters are not shown in ``.display()``.
