# problem.getInfeas

Purpose
Returns a list of infeasible primal and dual variables.
Topic areas
Solution, LP, Optimizer
Synopsis
`x, slack, duals, djs = problem.getInfeas()`
Error values

91 | A current problem is not available.
422 | A solution is not available.

Related controls
Double

FEASTOL | Tolerance on RHS.
OPTIMALITYTOL | Reduced cost tolerance.

Return value

x: list[int] | Integer array containing the indices of the primal infeasible variables.
slack: list[int] | Integer array containing the indices of the primal infeasible rows.
duals: list[int] | Integer array containing the indices of the dual infeasible rows.
djs: list[int] | Integer array containing the indices of the dual infeasible variables.

Further information
1. This function applies to linear and convex quadratic (including second order conic) problems only.
2. To find the infeasibilities in a previously saved solution, the solution must first be loaded into memory with the problem.readBinSol function.
