Compare arrays or rnages

[jakopak]

I have two arrays (2 dimensional) of same size. I would like to compare them if they are equal.
I have two ranges of same size. I would like to compare them too.

Doing it by loop is not feasble. Is there a better way?

Why is it not feasible to do it by loop? Looping it the only way to 'walk' through an array.

As you don't want to loop then I doubt you'll want to read this page which lists (probably) just about every bit of code you need to work with arrays.

Better stated: Doing it by loop is slow at least for ranges. Say I have large array or range on which I apply function. I would like to apply the function many times by loop. In each step n I want to test if the array(n)=arry(n-2). So the faster the check the better.

Looping through arrays is fast. It's looping through ranges that isn't
