在 MATLAB Online 中打开

a = 5;
b = [4,5];
sprintf('it has happened %d times in the flight, in the %d and %d second',a,b(1),b(2))
ans = 'it has happened 5 times in the flight, in the 4 and 5 second'

A general solution:

tmp = compose('%d',b);
tmp(2,:) = {', '};
tmp{2,end-1} = ' and ';
sprintf('it has happened %d times in the flight, in the %s second',a,[tmp{1:end-1}])
ans = 'it has happened 5 times in the flight, in the 4 and 5 second'
