basisstability

Purpose
Calculates various measures for the stability of the current basis, including the basis condition number.
Synopsis
basisstability(prob, type, norm, scaled)
Arguments
prob 
The current problem.
type 
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 
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 the stability values are to be calculated in the scaled, or the unscaled matrix.
Return value
The calculated value.
