@Preben Alsholm It works well. Thank you very much

## That's true, and more......

Your note is true.

And if changing add(a[r],r=i..j) to add('a[r]',r=i..j), I get message "Error, (in task) bad index into Vector" occasionally.

It seems depending on computer hardware.

My computer of 32 digits only support 2^30 entries. If more entries, maple returns "Error, (in Vector) integer too large in context"

## Chinese characters :)...

“文件夹” :)

By the way,can maple cloud work in China mainland in your computer?

## so......

So if and only if the first number of w is real and the rest numbers are conjugate symmetric, DFT of w has pure real numbers.If the number of rest numbers is odds,then the middle number should be conjugate symmetric to itself.So it must be a real number,is it?
