Info on vectors from within Maple 6 software vector example maple Stack empty.

Examples:
> linalg[vector](4,[1,x,x^2,x^3]);

[ 2 3]
[1, x, x , x ]

> array(1..3,[1,2,3]);

[1, 2, 3]

> type(%,vector);

true

> array(0..2,[a,b,c]):
> type(%,vector);

false

Attempt to parse string to variable for further use. LL array(1..4,[1,x,x^2,x^3]) parse maple :

From maple 5 books supposed to be able to use % to get the previous no. off the stack, does not work. % vector type maple false

using the variable to test for a vector does not work LL vector type maple false

Accidently discovered if i put in a parse comment, can then go back delete parse and 66 and 99, success. array\0028\1\002E\\002E\4\002C\[1\002C\x\002C\x\005E\2\002C\x\005E\3]\0029\ (vector type maple true

type with square brackets as text, then remove 66 then 99. 4 [1 x x 2^x 3]^linalg[vector] (vector type maple true

GG array(1..3,[1,2,3]) parse vector type maple : false

have found same result again removing 66 and 99 array\0028\1\002E\\002E\3\002C\[1\002C\2\002C\3]\0029\ vector type maple true

lets learn some more about parsing in maple. parse example maple Stack empty.

Examples:
> parse("a+b");

a + b

> parse("a+b:");

a + b

> parse("a+b;");

a + b

> parse("a+b:"):
> parse();

true

> parse("a+b;"):
> parse();

false

# Parse will generate errors on incorrect input

> parse("a++b");

Error, incorrect syntax in parse: `+` unexpected (4)

> parse("sin(3.0)");

sin(3.0)

> parse("sin(3.0)",statement);
