Clear variablename: clears that variable"s value intmin(int8) range: [-128, 127] randi(imax): generates random real number on [1,imax] Abs ; sign ; min ; max. Logical statements all: returns true only if all elements are true isequal: outputs 1 if all elements in two vectors are the same or. %s: string field width: the first number after %
