More on sequences
is simply an ordered collection of numbers or other Maple expressions separated by commas.
Here is an example of a sequence in Maple. Remember, a sequence can contain any mixture of numbers and other Maple expressions.
> myseq := 1, 5, x, z^2, 3;
You can pick out any member of a sequence by specifying its position in the sequence. For example, to refer to the third member in
There are several ways to generate sequences in Maple. The first is the method we used above: type in the sequence. This can be inconvenient when we need to generate large sequences, however. When the sequence has a simple pattern, Maple provides some more efficient methods for generating sequences. One such method is the seq command:
seq( i, i = 6..9 );
squares := seq( i^2, i = 2..5 );
Get the idea? In general, the first expression ( i^2 in the second example) is repeated in a sequence, with i changing as specified (from 2 to 5 in the second example). You can use letters other than i if you like.
