How can I integrate with the limits I want?

[jocuma]

Hi people again, 

I need to integrate between to limits 37 and 77 you can see in the graph image that I add,

now the integration that I do is all the graph and I want this values like a control.

is it posible to do?

thanks.

First you need to find out what array indexes relate to the x-axis values of 37 and 77 and only send that subset of the entire array to the integration. The Threshold function can be useful for that.

I have not gone myself, but probably same stuff was discussed in this post.

The above post talks about 'Area under Curve'.

I now what you say but... the threshold function give me an error :S

help please

thanks

The output of the threshold function is a fractional index. Round it to the nearest integer an us it to calculate the subset of elements you need. There is an array subset function that can actually extract the data for you from the arrays.
