You can create a row vector by using the index operator (:). The following statements show that you can use the index operator to count up, count down, or to create a vector of character values with numerical suffixes:

r = 1:5;
s = 10:6;
t = 'abc1':'abc5';

To create a vector based on an increment other than 1, use the DO function. For example, if you want a vector that ranges from to by , use the following statement:

u = do(-1,1,.5);
