Constrained nonlinear optimization

[MinaMaged2030]

Error -20071 occurred at an unidentified location

Possible reason(s):

Analysis: The input matrix is not positive definite.

when running my (Constrained nonlinear optimization) vi this error appears 

Any suggestions??

thanks in advance

Possible reason(s):

Analysis: The input matrix is not positive definite.  We can't see the input matrix -- maybe it is not positive definite.

Any suggestions??  See comments.  Attach code.  Attach data.

Sorry about that

In your problem, the inequality constraint minimum and maximum of the second inequality are both 155. Combining with the first inequality constraint, there is no solution satisfying the constraints. The error "The linearized problem has no feasible solution.The problem may not be feasible" was generated first,  but was not propagated correctly. It was covered by error -20071 later.
