I want to minimize a multivariate function which is dependent on 5 variables. (a,b,c,d,e) or (x(1),x(2),x(3),x(4),x(5)). I want to optimize/minimize this function to give me values of all 5 variables.
I need help in using this function. I am looking for exact code to optimization with fminunc that would work for me.
Below both equations are same first one has variables a,b,c,d,e and second has variables x(1),x(2),x(3),x(4),x(5).
Thanks

In your case, your objective functon f should accept a vector x and return f(x), such as
f = @(x) (-24951.7481672607*(x(3))*(x(5)))-....
