Again, the Matlab way...
if all(iswithin(x,Lo,Hi)) disp('Test: PASS') else disp('Test: FAIL') end
Don't need any loops...
The incorporation of the vectorized operations within Matlab is a prime reason for there to even _be_ a MatlabLearning to utilize the capabilities will serve well in the long run. (If don't, next thing will be you're posting here asking how to speed up a long computation... :) )
