Cell Array Indexing of HEX values

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'
