When converting a list which includes lists to a set, duplicate entries are dropped.

However converting a list with vectors to a set, no duplicate entries are dropped.

Any explanation to that behaviour?

a := {Vector(2, [1, 0]), Vector(2, [2, 0])}

{Vector[column](%id = 36893490347685388884), Vector[column](%id = 36893490347685389004)}

(1)

b := [Vector(2, [1, 0]), Vector(2, [2, 0]), Vector(2, [1, 0])]

[Vector[column](%id = 36893490347747359308), Vector[column](%id = 36893490347747359428), Vector[column](%id = 36893490347747359548)]

(2)

c := convert(b, set)

{Vector[column](%id = 36893490347747359308), Vector[column](%id = 36893490347747359428), Vector[column](%id = 36893490347747359548)}

(3)

d := [[1, 0], [2, 0], [1, 0]]``

[[1, 0], [2, 0], [1, 0]]

(4)

e := convert(d, set)

{[1, 0], [2, 0]}

I'm getting a strange error today when trying to save a file on the network. Rebootet machine, no change.

Any hints?

Can someone tell me why there is a difference between global and local variables in this code?

...cannot determine if this expression is true or false

Sorry to bother you with a basic question again.

How do I get both the indexes and the values of a table?

Anyone else experiencing problems uploading Workbooks as MaplePackage to MapleCloud.

Very often it is not possible to upload a workbook as a package, but just as a normal Maple file. Takes a couple of tries with opening the file until it is possible.
