we have two cell arrays that we would like to compare. the first of size 3x67 call it A and the second is of size 3x2 call it B. each row of the two cell arrays represent the data for the same day so we would like to compare the cells in the first row of A by the cell in the first row of B and so on. we are looking after the columnS "fof2" and "hmf2" from the cell in B, we will check the timimg in hours and minutes from the Date columns between this cell and the cells in A, and add to each cell in A the corresponding data for the columns "fof2" and "hmf2", it is not neccesary that we find exactly matching timings it is enough for them to be with in +-15mins range from each other. I am having an issue with the comparison between cell arrays, so if anyoe can help me in finding an effecient and easy way to do this, I attach the two cell array that I am working with.
Thanks in advance.

Ran in:
I am not certain what result you want.
Try this, and if it works, loop through the elements of ‘A’ and ‘B’ for all the necessary combinations. Note that in at least one for the ‘B’ table, ‘hmF2’ is actually 'hmF2 ' with an extra space that creates problems with the variable name referencing. If all the resulting timetables have the same variables in the same locations, numerical referencing will work.
