PsiDualLower()

PsiDualLower (cell, [optimization])

PsiDualLower displays the dual lower value for the referenced constraint or decision variable in an optimization model.

• cell is the Excel reference for the constraint or decision variable
• optimization (optional) is the optimization index if running multiple optimizations, i.e. "2" would indicate the 2nd optimization. 

If deploying your Excel model to the Rason server, enter this function in a blank cell on the spreadsheet to receive the dual lower value, for either a constraint or decision variable, in the results.
