Bit depth of the generating matrices



.. toctree::
   :hidden:
   :maxdepth: 1



**Specification**

- *Alias:* None

- *Arguments:* INTEGER

- *Default:* 0


**Description**


Use this option to set the number of rows in the generating matrices, or, equivalently, the number of bits of the integers that encode the generating matrices.
This keyword must be specified when using the :dakkw:`method-sampling-sample_type-low_discrepancy-digital_net-generating_matrices-inline` or :dakkw:`method-sampling-sample_type-low_discrepancy-digital_net-generating_matrices-file` options to specify generating matrices.
It cannot be specified when :dakkw:`method-sampling-sample_type-low_discrepancy-digital_net-generating_matrices-predefined` generating matrices are chosen.
