Presumably the rest of the explanation is in the source code, which you didn't include in your message. This is a text-mailing-list, and many of us cannot see attachments, and many others of us cannot see html. Please tell your email program to use plain text, not html. Please paste any attachments into the same text message, unless it's too big. In that case, you'd need to paste a link instead, but many people won't be able and/or willing to follow such links. -- DaveA

Sorry for this inconvenience. Since my file is a little large, I think it will be more difficult for fellows to check. I will now paste the attachment below.
The file for T(E) consists of two columns, the first is E and the second is T(E). What I want is to integrate this function in a certain range.
E T(E)
