Hi, you can compare the strings of the key with the user input, and then use that index to retrieve the value:
UserInput = "key1";
MyData = ["key1" "value_1";
"key2" "value_2";
"key3" "value_3"];
% look for the index of the "key"
Idx = contains(MyData(:,1),UserInput);
if any(Idx)
% extract the coressponding "value"
MyOutput = MyData(Idx,2);
else
disp('no matching key found')
end
MyOutput
MyOutput = "value_1"

Take a look at the containers.Map function.
