search and retrieve data from cell array

I have got a cell array containing a column of 1000 (thousand) 2x2 doubles.

Could someone advise on the most efficient way to search for certain numbers in those doubles? And if found (within an error range), to save them in a separate table?

Many thanks in advance!

The most efficient way would probably be to use a loop. The easiest way might be to use cellfun. Probably the best way would be to have stored your data in one ND array, then you could write better, simpler, vectorized code:

The easiest way I know of is to use cellfun. For instance if you were looking for numbers that are greater than 2

arraysWithNumbersGreaterThan2_IX = cellfun(@(x) any(any(x > 2)), inputArray)
seperateList = inputArray(arraysWithNumbersGreaterThan2_IX);

If you want to find arrays that have 1, 4, or 7 in them

arraysWithCertainNumbers_IX = cellfun(@(x) any(ismember([1,4,7],x)), inputArray)
seperateList = inputArray(arraysWithCertainNumbers_IX);
