c=argmin f(a,b).where both a,b are M*1 and N*1 column matrices respectively.
How to get a,b for minimum value of f(a,b) from matlab

What does it mean to find the minimum value or index of two vectors with different lengths? Can you provide a short example of inputs and desired output?

Are you looking for something like this?
Let a,b be your column matrices.
[a,b] = meshgrid(a,b) ; % make them a matrix
F = f(a,b) ; % evaluate your function, use element by element operations in f
[val,idx] = min(F(:)) ;
amin = a(idx) ;
bmin = b(idx) ;
Have a look on fmincon.
