Variables let you give names to values and refer to them later. You have
already seen variables in many of the examples. The name of a variable
must be a sequence of letters, digits and underscores, but it may not begin
with a digit. Octave does not enforce a limit on the length of variable
names, but it is seldom useful to have variables with names longer than
about 30 characters. The following are all valid variable names |
