Accessing each matrix in a cell array of size ~8GB and filter it

1 view (last 30 days)
I have the follwing cell array,
I am trying to access each cell in it and check the 4th and 5th column inside each matrix in it to see if they satisfy a certain condition. I kinda have an idea how to do it in a foor loop, but it is extremely huge with a size of nearly 8GB, so I assume a for loop will take forever to go through all of it. So is there any more effecient way to access each and every matrix and filter it according to our conditions?
Thank you in advance.

A loop is the efficient solution. Simply try it.
If you have >= 16 GB of RAM, this array should be processed without problems. The subarrays are small and accessing them does not duplicate the data.
