Hello

this is programm to minimize function by Lagrange Multiplier method with three variables: (h the function ,g is the constraint)

syms x,y,z, lam

gradh = jacobian(h,[x,y,z])

gradg = jacobian(g,[x,y,z])

lagr = gradh - lam*gradg

My question is:

how can I do if I have in the function N variables??

(Example:f=sum 2*x_i ) i=1:k

And thank you
