Synopsis
problem.addNlpCoefEvalErrorCallback(nlpcoefevalerror, data=None, priority=0)
nlpcoefevalerror(cbprob, cbdata, col, row)
Arguments
nlpcoefevalerror 
The function to be called when an evaluation fails.
data 
Address of a user-defined object, which can be used for any purpose by the function. data is passed to nlpcoefevalerror as cbdata.

cbdata 
The user-defined object passed as data to problem.addNlpCoefEvalErrorCallback.
col
