Detailed Description

The in-memory representation of the <linearConstraintCoefficients> element.

Remarks:

if a large part of the problem is linear, then store this is the standard sparse format, either by column or row. There are three arrays, an array of nonzero values, an array of either column or row indices and then a pointer to the start of each column or row.
