hello,
please could you help me to find the minimum of the following multiple-variable polynomial with fmincon in the intervals ;
lb=[0.1,0.000001,0.001,0.001,0.01]; ( lower )
ub = [1,0.00001,0.01,0.01,0.1]; (Upper)
The starting point is starting x0=[0.3,0.000003,0.009,0.001,0.1]
f=3.9964e-005+0.00033638*x(1)-8.7619e-006*x(2)+2.4143e-007*x(3)-2.4334e-005*x(4)-0.0001409*x(5)+0.001094*x(1)^2+5.8132e-005*x(1)*x(2)-5.1176e-005*x(1)*x(3)+8.7935e-007*x(1)*x(4)+4.1419e-005*x(1)*x(5)+1.3277e-005*x(2)^2-9.5541e-006*x(2)*x(3)-2.8391e-006*x(2)*x(4)+4.3647e-007*x(2)*x(5)-2.9051e-005*x(3)^2-7.9979e-007*x(3)*x(4)-1.0696e-007*x(3)*x(5)-2.344e-005*x(4)^2-3.9174e-008*x(4)*x(5)+0.00035851*x(5)^2-1.0287e-005*x(1)^3-2.1388e-006*x(1)^2*x(2)-8.2328e-007*x(1)^2*x(3)-5.6803e-006*x(1)^2*x(4)+1.0406e-006*x(1)^2*x(5)-7.8119e-007*x(1)*x(2)^2-4.3043e-005*x(1)*x(2)*x(3)+9.3754e-007*x(1)*x(2)*x(4)+8.1257e-007*x(1)*x(2)*x(5)+3.5604e-005*x(1)*x(3)^2-6.9328e-007*x(1)*x(3)*x(4)-2.4979e-007*x(1)*x(3)*x(5)+1.2842e-005*x(1)*x(4)^2-1.7351e-006*x(1)*x(4)*x(5)+2.8136e-006*x(1)*x(5)^2+1.86e-005*x(2)^3+1.2037e-006*x(2)^2*x(3)+6.0567e-006*x(2)^2*x(4)+4.6669e-006*x(2)^2*x(5)+5.6196e-006*x(2)*x(3)^2-4.5222e-007*x(2)*x(3)*x(4)+1.6565e-007*x(2)*x(3)*x(5)+1.9366e-006*x(2)*x(4)^2-1.98e-006*x(2)*x(4)*x(5)-1.7126e-006*x(2)*x(5)^2-1.3184e-005*x(3)^3+2.3342e-005*x(3)^2*x(4)+1.7295e-006*x(3)^2*x(5)-3.3598e-007*x(3)*x(4)^2-1.9132e-006*x(3)*x(4)*x(5)+2.2644e-006*x(3)*x(5)^2-4.2793e-006*x(4)^3-1.3026e-006*x(4)^2*x(5)+8.2559e-006*x(4)*x(5)^2+2.6853e-005*x(5)^3-2.0448e-005*x(1)^4-9.343e-006*x(2)^4+2.8214e-005*x(3)^4+2.3133e-005*x(4)^4+5.786e-006*x(5)^4

Hi,
have you tried anything yourself?
Please study the documentation on fmincon, and particularly the example in there. This should give you enough guidance to solve your problem.
Cheers,
Harald
