Re: warning: sqp: QP subproblem failed to converge in 200 iterations

see http://www.gnu.org/software/octave/doc/interpreter/Quadratic-Programming.html

and http://www.gnu.org/software/octave/doc/interpreter/Linear-Least-Squares.html#doc%2doptimset

you want to set the options for MaxIter higher.

Something like optimset(MaxIter,201)

Hello,

I am dealing with an iteration where in each step a minimization problem

min_{a_i<=x_i<=b_i})(real(b)-real(f(x_1,x_2,x_3,x_4,x_5,x_6,x_7)).^2+(imag(b)-imag(f(x_1,x_2,x_3,x_4,x_5,x_6,x_7)).^2) is solved using sqp.

However, I receive every time the following error:

warning: sqp: QP subproblem failed to converge in 200 iterations

How can I adjust the number of iterations of qp?

(It should converge as it does if I compute f in a different way, but this way is slightly faster.)

Best regards,
