Hi, I am quite new to MATLAB so this may be simple.
I have two variables called Filtered_Gear_rpm and Filtered_NES_rpm that have data in each that make up an array of 40000x1 (for each variable). I have data over a time period of 5 seconds.
The aim is to extract data from each variable between 2 and 3 seconds (16,000th element to 24,000th element) and input each data point into an equation (that contains both Filtered_Gear_rpm and Filtered_NES_rpm) which will then store these values in an array or matrix.
The equation contains both Filtered_Gear_rpm and Filtered_NES_rpm so i presume these will have to be in the same loop.
I have tried using a for loop but I have got no where with it however I think this is the right idea.

Just index, no loop needed.
Filtered_Gear_rpm=rand(40000,1);%sample data
Filtered_NES_rpm=rand(40000,1);%sample data
z=exp(x).*exp(y)+log(x).*log(y)%whatever you equation is
z = 8001×1
