Hello,
I have a HEX cell array and I use importdata function to import them.
a = importdata('C:\User\Desktop\text.txt');
It gives me 2x1 cell '0F 04 0A 0E 1E 2F' and '3E 2A 1F 03 05 0A'
For example, I want to take 0E from there, how can I index this element? Thank you.

a = {'0F 04 0A 0E 1E 2F', '3E 2A 1F 03 05 0A'};
C = squeeze(split(a,' '))
C = 2×6 cell array
{'0F'} {'04'} {'0A'} {'0E'} {'1E'} {'2F'} {'3E'} {'2A'} {'1F'} {'03'} {'05'} {'0A'}
C{1,4}
ans = '0E'

Can we write like C(1, 4:5) or something like that for cell arrays?

Try it and see:
a = {'0F 04 0A 0E 1E 2F', '3E 2A 1F 03 05 0A'};
C = squeeze(split(a,' '));
C(1, 4:5)
ans = 1×2 cell array
{'0E'} {'1E'}
Seems to work.
Note that subscripting a cell array with parentheses ( ) like that gives you another cell array. To get the contents of the cells instead, use braces { }:
C{1, 4:5}
ans = '0E'
ans = '1E'
And you may want to concatenate those 2 outputs together, using square brackets [ ]:
[C{1, 4:5}]
ans = '0E1E'
Another example:
[C{2,:}]
ans = '3E2A1F03050A'
