The question is very basic. Did you read the "Getting started" chapters of the documentation already and processed Matlab's Onramp? This would help you efficiently to solve such problems.

Hi Manav,

You can do it via the following code:

s = 'orange';
v = [1 2 5];
for i=1:numel(v)
    fprintf("Char at %d is %s\n", v(i), s(v(i)));
end
