Detailed Description

LP interface for Clp

LP interface

LP interface struct for HiGHS

internal data for Mosek LPI

LP interface

Store several statistic values about the LP. These values are only needed in order to provide a rudimentary communication, e.g., there are asserts that check the number of rows and columns.
