Initializing help system before first use

problem.bndSA

Purpose
Returns upper and lower sensitivity ranges for specified variables' lower and upper bounds. If the bounds are varied within these ranges the current basis remains optimal and feasible.
Topic areas
Sensitivity Analysis, LP
Synopsis
lblower, lbupper, ublower, ubupper = problem.bndSA(colind)
Argument
colind 
Integer array containing the indices of the columns whose bounds' ranges are required.
Return value
lblower 
Double array containing the variable lower bound lower range values.
lbupper 
Double array containing the variable lower bound upper range values.
ublower 
Double array containing the variable upper bound lower range values.
ubupper 
Double array containing the variable upper bound upper range values.
Further information
1. problem.bndSA can only be called when an optimal solution to the current LP has been found. It cannot be used when the problem is MIP presolved.
2. Argument colind may contain xpress.var objects instead of indices.
