Accessing data in a cell array

Hello, I have a (1x7) cell array that contains as follows:

cell_array = 

Columns 1 through 4

      [10000x8 char]    [10000x6 char]    [10000x6 char]    [10000x1 double]

Columns 5 through 7

      [10000x64 char]    [10000x10 char]    [10000x1 int]

I want to access some part of cell_array, i.e. the 100 line of data in cell_array from row 2101 to row 2200. Would you please help me how to refer those elements of cell_array?

Thanks a lot!

Thanks for your advice. However, would you please explain more? As in case of database, I would like to select all columns of some records (rows) only. In case of a cell array, I cannot use the following command:

cell_array(1,1:7){2101:2200,:}

This gives an error, "()-index must appear last in an index expression."

How can I do what I want? Thanks in advance.

Hopefully this will give you some clues:

c = cell(1,2);
c{1} = ['abcd';'efgh'];
c{2} = [1,2,3,4;5,6,7,8];
c = 

      [2x4 char]    [2x4 double]

string = c{1}(2,2:3)

string =

fg

number = c{2}(1:2,3:4)

number =

       3     4
       7     8

Thanks a lot for your answer.

BTW is there any way to handle strings and numbers together?

I understand from your answer that it is not possible to handle strings and numbers together within a cell.

Please clarify this point. Thank you!

MATLAB really wants you to keep strings and numbers separate. Your options are to convert the numbers to strings (e.g., num2str() ) or write them both to cells.
