How to get the number of the minimum element in matrix for example

for i=0:10
  f(i)=i^2-10*i+2
  argument to find i that minimize the function 
end

i=0:10;
f=i.^2-10.*i+2;
[fmin,imin]=min(f);  % minimum to nearest integer value

To solve for the minimum, couple of ways. Using numerical w/o the symbolic toolbox one is

fsolve(@(x) polyval(polyder([1 -10 2]),x),1)
