The magic_number command

magic_number id value

The magic number command is used to modify internal program values. Each id corresponds to a parameter. Currently two ids, 1 and 2, are supported. They are used to modify the numbers SNAP uses to detect a singularity in the normal equations. id=1 is a proportional measure and id=2 is an absolute measure. The command mulitplies these measures by value. That is, if value is greater than one then singularities are more likely to be detected.
