Minimizing individual element of a vector that consists of 2-variables function

I have a new user of Mathcad prime 2.0. I have never used mathcad before.

I have a question about minimizing.

I have a one-column vector, v, with n rows which consists of n functions that involve the variables a and b.

i.e. v:=[ F1(a,b) , F2(a.b), F3(a,b) ....Fn(a,b) ]

I want to find a value of a and b such that all individual n functions, from F1 to Fn, are minimized or equal zero.

all the functions are similiar but different.

I would like mathcad to return 1 value of a and 1 value of b such that all the function is minimized,

but not 1 set of a,b for each function and ending up with n sets.

Can someone tell me what kind of mathcad function can do that? I tried to look up in mathcad help, but 1 have no luck

Thank you very much
