SetNonzerosPerInequality Method

Set the estimate for number of non-zeros per row. In some cases we know how many rows we want to create but not how many non-zeros they will have. To avoid excessive reallocations this class attempts to guess the number of non-zeros that will created using the estimate set by this function. Usually you should not need to call this function but in some corner cases performance can be improved by tweaking this estimate. The function returns the previous estimate. If the function is called with a negative estimate argument then the estimate is not changed. So SetNonzerosPerInequality(-1) queris the current estimate.
