I have 2 , 1×20 Matrices. Say,Matrix A and B are my 2 Matrices. What I would like to do is Sum of (A_i + A_i+1)*(B_i + B_i+1). Where A_i @ i=0 is the first term of matrix A and A_i+1 the term after that for all 20 terms. Same for B. How could I do that?

solve() generically outside of the loop and then subs() or matlabFunction() to get code executed for each loop instance.

I haven't tried this, but it sounds straightforward.
Decision variables: x(1) = x, x(2) = y, x(3) = R.
100 nonlinear inequality constraints: (x(1) - a(i))^2 + (x(2) - b(i))^2 - R^2 <= 0
Objective function: R = x(3)
Bounds: ll = min(min([a,b])), mm = max(max([a,b]))
lb = [ll,ll,0] , ub = [mm,mm,Inf]
Call fmincon from a reasonable start point, such as [(ll+mm)/2,(ll+mm)/2,abs(mm)]
