How can I extract the order of a number in a list?

e.g.

L:=[1,3,5,8,9];

Order(3)=2

Order(9)=5

I need to delete certain components of a vector, I know if it was a matrix I could use DeleteRow and DeleteColumn but it does not work for a vector, how can I do that?

e.g.

A:=<2,10,5,7>;

n:=2 (delete second component) ??

A:=<2,5,7>

Is there any function that easily gives us the max value of a matrix?

Hi,

I have a matrix with 3 columns and I want to change the order of columns 2 and 3. In fact  column to must be column 3 and vice versa. I was wondering if there is a function that I can use? (the number of rows is variable)

Thanks,

Hi,

I need to copy and paste the output of maple (that usually are in blue color) into word. In fact I want them to be shown exactly in the same form that we can see in maple. Is there any way to do this?

Thanks in advance,

Ibo
