As an outline,
for index_variable = start_value : increment : final_value
if some_array(index_variable) satisfies some condition
calculate new value
some_array(index_variable) = new value
end
end

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

% declare input variables
numberSamples = 4;
userSamples = [2 12 9 20];
minValue = 10;
% call the function (preferably from command window (>>)
dataSamples = AdjustMinValue(numberSamples,userSamples,minValue)
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

My professor or textbook were no help.
... which is to say that this is a homework question.
