You need to set a value called theMax and set it to -inf before the loop:
theMax = -inf;
theMin = +inf;
Then in the loop check if A(i) is less than theMin or more than theMax.
if A(i) < theMin
If it is, set the min or max to the current value of A(i). Give it a try and if you need more help with your homework give you most recent code version.

If m is your array:
mMin = inf;
for k = 1 : numel(m)
if m(k) < mMin
mMin = m(k);
This should work for any number of dimensions.
