Hi dear all, In my programming, there is no feasible solution when I added some constraints. I want to know that if there is no feasible solution. Does it mean, there is a conflicts in my constraits?
thank u

You might want to try the suggestions in the documentation for what to do when there is no feasible point found.

Hi Alan, thank u for ur reply. However, my question is that , before, there is a feasible solution, When i added some constraints, there is no feasible soultion. So, does it mean there is a conflicts among my constraints?
thank u

The answer is "maybe." I suggest that you look at the documentation link that I gave.

Hi, i tried to use fmincon (interior-point algorithm) to solve quadratic integral problem which is subject to linear and nonlinear constraints, but i faced an exitflag (-2) and an error message (no feasible solution found). However, i tried to converge fmincon to an feasible point by checking the nonlinear constraints through set the objective function to zero, in order to get another initial point but i faced the same message (no feasible solution found). Any suggestions can help. Thanks
