It is possible to insert a while loop inside a for loop?
This is very dangerous code, because there is a finite possibility that the inner while loop will never stop, locking up the program forever.
It also seems overly complicated.

I think all you need is a single FOR loo. Here's what I would do. (Of course you need to decide what to return if the condition is never met, for example, so modify as needed).
(Left to right: reshape array, FOR loop, multiply, array subset, greater, search array, index array)
@jwscs wrote:@altenbach thx for mentioning it, if for any subarray the i and (i+1) differs less than 10*i, the while will not exit
or did you mean something else?
Yes, just run your code a couple of times. on occasion it will continue forever!
(Yes, if the condition is never met and we run out of elements while processing a row, index array will return two zeroes forever, never meeting the > condition. If you would change the condition to "greater or equal" it will return zero like my code when it runs out of elements and no match has been found because we get a 0=0-->TRUE.)
Still, my code is probably simpler. 😄
It might be cheapest (especially with huge arrays) to avoid "reshape" and "array subset" and just operate on the unmodified array. For the inner loop, use a conditional FOR loop.
This code gives about the same result and does all operations on scalars, limiting memory use.
