# problem.estimaterowdualranges

Purpose
This subroutine is deprecated and will be removed in a future release. Use problem.estimateRowDualRanges instead.
Performs a dual side range sensitivity analysis, i.e., calculates estimates for the possible ranges for dual values.
Synopsis
`problem.estimaterowdualranges(rowind, iterlim, mindual, maxdual)`
Arguments

rowind | rows (i.e., xpress.constraint objects, indices, or names) to analyze.
iterlim | Effort limit expressed as simplex iterations per row.
mindual | Estimated lower bounds on the possible dual ranges.
maxdual | Estimated upper bounds on the possible dual ranges.

Further information
This function may provide better results for individual row dual ranges when called for a larger number of rows.
