problem.getinfeas

Purpose
Returns a list of infeasible primal and dual variables.
Synopsis
problem.getinfeas(x, slack, duals, djs)
Arguments
x 
Array to store the primal infeasible variables. May be None if not required.
slack 
Array to store the primal infeasible rows. May be None if not required.
duals 
Array to store the dual infeasible rows. May be None if not required.
djs 
Array to store the dual infeasible variables. May be None if not required.
Example 
x = []
slack = []
p.getinfeas(x, slack, None, None)
print("getinfeas --> x and slack:", x, slack)
Further information
To find the infeasibilities in a previously saved solution, the solution must first be loaded into memory with the problem.readbinsol function.
