# SetNonzeroThreshold Method

Set the threshold value for non-zeros. If the number of non-zeros in the internal buffer exceeds the threshold then all rows currently in this instance are flushed to the corresponding Xpress problem instance. Usually you should not need to call this function but in rare cases performance may be improved by tweaking this value. The function returns the previous threshold value. If the threshold argument is negative then the threshold is not changed. So SetNonzeroThreshold(-1) just queries the current threshold.
