Best Answer

You mean something like this:
% Make some sample data.
m=rand(1, 10)
% See where it exceeds 0.5.
biggerThanPoint5 = m > 0.5
% Make some other array that we want to act upon.
out = 11 * ones(1,10)
% Set out = 99 where m>0.5
out(biggerThanPoint5) = 99
Results in command window:
m =
    0.4898    0.4456    0.6463    0.7094    0.7547    0.2760    0.6797    0.6551    0.1626    0.1190
biggerThanPoint5 =
     0     0     1     1     1     0     1     1     0     0
out =
    11    11    11    11    11    11    11    11    11    11
out =
    11    11    99    99    99    11    99    99    11    11
