MATLAB: Is it Possible to store an if Condition in a String to manipulate later

Question

Am I able to do something like this in Matlab? Please advice

aaa = 'r > 0 && r < 5 '; if (aaa) r = r+1; end

Answer 1

you can do that using eval

r=1;
aaa = 'r > 0 && r < 5 '; 
if eval(aaa) 
  r = r+1; 
end
disp(r);
