How can i find a specific member of an array?

Hello everybody,

I have an array full of calculated values. I need to find a fraction of it where it meets a specific condition and plot it.

How can i do that?

Okay, so for example i have an array like

A = [5 5 5 2 3 4 5 6 7 8 7 6 5]

and i only want to run my script for the part the values increase, in this case i want to create the array, B = [2 3 4 5 6 7 8]

Answer 1

idx=find(diff(A)>0);
idx=[idx idx(end)+1];
B=A(idx)

Thank you so much. After that, how do I find the indices of these values?

[Birdman]

The indices are stored in idx array.

idx =

     4   5   6   7   8   9   10
