How can I solve for six variable using six equations using the Optimization toolbox such that the variables are between 1 and 0?

ConstStr

N7 = 3.135E+00*N1*N2,

N8 = 4.100E-01*N2*N6,

N9 = 1.381E+01*N1*N4,

N10 = 7.610E+01*N2^2*N3,

N11 = 1.720E+05*N2*N3^2*N5^3,

N12 = 4.034E+04*N3*N5^2,

N13 = 2.615E+04*N2*N3^2*N5^2,

N14 = 3.826E+44*N1*N3*N5^2,

N15 = 1.458E+03*N2*N3*N5,

N16 = 2.435E+04*N1*N3^2*N5,

N17 = 1.186E+08*N3^2*N5^3,

N18 = 7.511E+02*N3*N5,

N19 = 6.874E+02*N3*N5;

Function

N1+N2+N3+N4+N5+N6+N7+N8+N9+N10+N11+N12+N13+N14+N15+N16+N17+N18+N19 = 1;

0.1962*(N2+N7+N8+2*N10+N11+N13+N15)-0.6575*(N1+N7+N9+N14+N16) = 0;

0.0557*(N3+N10+2*N11+N12+2*N13+N14+N15+2*N16+2*N17+N18+N19)-0.4698*(N4+N9) = 0;

0.0099*(N5+3*N11+2*N12+2*N13+2*N14+N15+N16+3*N17+N18+N19)-0.3525*(N6+N8) = 0;

0.0557*(N1+N7+N9+N14+N16)-0.1962*(N4+N9) = 0;

0.0099*(N2+N7+N8+2*N10+N11+N13+N15)-0.6575*(N6+N8) = 0;

Hey! I found your post really insightful, especially the part about the challenges of working with MATLAB assignments. I faced similar struggles, which is why I decided to try out www.matlabassignmentexperts.com. The best thing that attracted me was that I could directly contact the expert via WhatsApp at [phone] or email them at [e-mail]. They were incredibly responsive and helped me understand the concepts better while completing my assignments on time. I highly recommend giving them a try!
