Arguments

type

Which information to return. Possible values:

0	Condition number of the basis
1	Stability measure for the solution relative to the current basis
2	Stability measure for the duals relative to the current basis
3	Stability measure for the right hand side relative to the current basis
4	Stability measure for the basic part of the objective relative to the current basis

norm

Which norm to use. Possible values:

0	Use the infinity norm
1	Use the 1 norm
2	Use the Euclidian norm for vectors, and the Frobenius norm for matrices

scaled

If false, work on the unscaled matrix
