Using MATLAB. Determine when 'hello world' message occurs (index and time). Print result to command window.

Answer 1

MATLAB Code:

% Using MATLAB command determine when 'hello world' message occurs

% Storing messages in a vector
mesgs = {"", "", "", "", "", "", "", "hello world", "today is", "how are you", "what are you doing", "good bye", "", ""};

% Storing time in a vector
time = [1200 1205 1225 1240 1245 1255 1325 1330 1342 1354 1400 1409 1410 1424];

% Finding index of message hello world
idx = find(strcmp(mesgs, "hello world"));

% Printing index and time
fprintf("\n Message hello world occurs at index %d \n", idx);
fprintf("\n Message hello world occurs at time %d \n", time(idx));
