@acer Hi friend, I was wondering how can I correct Tomleslie's latest program using the CoefficientList function as you suggest? I appreciate your answer in advance. And sorry to bring this old topic again.

@acer I'm not that interested in efficiency at the moment. For now I am just generating some vectors to do some operations. Thank you.

@acer Thanks for the reply. Quick question, if I wanted to expand the product, how can I adjust the above command?

Edit: I already saw that I can use

map(expand@`*`@op,a1);

@Kitonum Thank you for the replay. The 'mul' command isn't working for me, I get the error 'expects 2 arguments, but received 1'. Maybe you could help me.

 

a := {x+1,x+2,x^2+1,x^2+x+2};
a1 := combinat:-choose(a, 3);
map(mul, a1);
Error, invalid input: mul expects 2 arguments, but received 1

 

 

@acer 

In both cases, do you know how can I change the scale on the x-axis to be from 0 to 256 and not from 0 to 1?

 

@Carl Love 

Thank you very much for your help!

@mthkvv 

Thank you very much for the answer!

@tomleslie 

Thank you very much for the help!

@acer 

Thank you very much for your help, the program works very well.

@tomleslie

Thank you very much for the alternative answer.

@acer That's a very elegant solution, thank's a lot for the help!

@acer Thank you for the answer!

I'm going to perform a Matrix multiplication, something like this:

I think it's an easy way to achieve it (or maybe not).
