MATLAB: Textscan Usage. One character in one cell.

textscan

I have a text file in which following characters are written

ABCDE

I want to store it in a cell array of order 1 X 5 , with each character in one cell.

I tried using Textscan as follows, but it gives only 1X1 cell with all characters in one cell.

Kindly Help.

Hi,

>> fid = fopen('in.txt')
>> data = textscan(fid,'%c')

data =

    [5x1 char]
>> fclose(fid)

data is a 1x1 Cell which contains a 1x5 Char Array. And in the case you really need a cell you can use mat2cell:

new_data = mat2cell(data{1},ones(numel(data{1}),1),1)

Loading txt into a cell.
Then do whatever you want with the cell. In this example, line 69 will be 99.
Then write the cell into a txt.

% Read txt into cell A
fid = fopen('test.txt','r');
i = 1;
tline = fgetl(fid);
A{i} = tline;
while ischar(tline)
    i = i+1;
    tline = fgetl(fid);
    A{i} = tline;
end
fclose(fid);
% Change cell A
A{69} = sprintf('%d',99);
% Write cell A into txt
fid = fopen('test2.txt', 'w');
for i = 1:numel(A)
    if A{i+1} == -1
        fprintf(fid,'%s', A{i});
        break
    else
        fprintf(fid,'%s\n', A{i});
    end
end
