How to integrate a discrete sequence

Hello

How to integrate a discrete sequence if we can't find out the
equation of the sequence.It's a onedimensional vector.

Any suggestions will be appreciated!

Thanks!

Hi jinlei!

You can use the trapz() function. Read help trapz. Post back if you
have questions.

Why not use numericalk integration techniques?

So the trapezoidal integration is not a numerical integration technique?

Hello,

The trapezodal rule is only one of all the possible ways to numerical
solve an itegral. Thus you were right!
I only tried to hint in other directions ifmore accuracy is needed.
