How to find the conflicts in the model when use the MATLAB optimization tool?

Hi dear all,

I used the MATLAB optimization tool to solve a nonlinear model. The result I got is like the following : No feasible solution found.

fmincon stopped because the predicted change in the objective function is less than the default value of the function tolerance but constraints were not satisfied to within the default value of the constraint tolerance. Could you tell me does it mean there is a conflict in my model?

how can I find where is the conflicts? I used the CPLEX before to do the linear model. There is a .LP file after runing the CPLEX file. With the help of the .LP file, I can not find where is the conflict, so could you tell me how can I find what is wrong with the model? Is there sth like .LP file in the MATLAB as well?

Thank you for your great help

The documentation has some suggestions on what to do for this case.
