EXERCISE 3-6

Generate a three-dimensional array containing the first eight positive natural numbers and whose three indices vary from 1 to 2. Access its operands and display its internal structure.

>> pretty(sym(maple('tridimen:=array(1..2,1..2,1..2,[[[1,2],[3,4]],[[5,6],[7,8]]])')))

>> pretty(sym(maple('tridimen')))

array(1 .. 2, 1 .. 2, 1 .. 2, [

(1, 1, 1) = 1

(1, 1, 2) = 2

(1, 2, 1) = 3

(1, 2, 2) = 4

(2, 1, 1) = 5

(2, 1, 2) = 6

(2, 2, 1) = 7

(2, 2, 2) = 8

])

>> pretty(sym(maple('op(eval(tridimen)) ')))

[1 .. 2, 1 .. 2, 1 .. 2], [(1, 1, 1) = 1, (1, 1, 2)= 2, (1, 2, 1)= 3,

(1, 2, 2)=4, (2, 1, 1)=5, (2, 1, 2) = 6, (2, 2, 1) = 7, (2, 2, 2) = 8]

>> pretty(sym(maple('op(1,eval(tridimen)) ')))

[1 .. 2 1 .. 2 1 .. 2]

>> pretty(sym(maple('op(2,eval(tridimen)) ')))

[(1, 1, 1) = 1 (1, 1, 2) = 2, (1, 2, 1) = 3, (1, 2, 2) = 4,]

(2, 1, 1) = 5, (2, 1, 2) = 6, (2, 2, 1) = 7 (2, 2, 2) = 8]
