As an outline,
for index_variable = start_value : increment : final_value

calculate new value
some_array(index_variable) = new value
end
end

Ran in:
numberSamples = 4;
userSamples = [2 12 9 20];
minValue = 10;
for k = 1:numberSamples
if userSamples(k) < minValue
userSamples(k) = 2*userSamples(k);
end
end
userSamples
userSamples = 1×4
4 12 18 20

Ran in:
% declare input variables
numberSamples = 4;
userSamples = [2 12 9 20];
minValue = 10;
% call the function (preferably from command window (>>)
dataSamples = AdjustMinValue(numberSamples,userSamples,minValue)
dataSamples = 1×4
4 12 18 20
function dataSamples = AdjustMinValue(numberSamples,userSamples,minValue)
dataSamples = userSamples;
for k = 1:numberSamples
if userSamples(k) < minValue
userSamples(k) = 2*userSamples(k);
end
end
% assign it desired variable name
dataSamples = userSamples;
end
