The DO function creates a row vector that contains a sequence of evenly spaced numbers.

The arguments to the DO function are as follows:

start

is the starting value for the series.

stop

is the stopping value for the series.

increment

is an increment value.

The DO function creates a row vector that contains a sequence of numbers starting with start and incrementing by increment as long as the elements are less than or equal to stop (greater than or equal to stop for a negative increment). This function is a generalization of the index creation operator (:).

The following statements show examples of using the DO function:

i = do(3, 18, 3);
k = do(3,  0, -1);
print i, k;
