FEASTOL 
Tolerance on RHS.
OPTIMALITYTOL 
Reduced cost tolerance.

Return value
x 
Integer array containing the indices of the primal infeasible variables.
slack 
Integer array containing the indices of the primal infeasible rows.
duals 
Integer array containing the indices of the dual infeasible rows.
djs 
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.
