How can I display all elements of an array in a single row?

hi, if I have an array, how I can display all elements in single row if I did not know the length of that row(i did not know the no. of columns) . where the size of rows is not equal

 for ex.
A=CGCKCCD?QDCQC??FE?N?NBCBNM?AEZE*GAAWE?E-GQE?R?N??Y
  G?GRHTHYH?H*HMHDHPH?HLHWGMHH?Y?AHCGYGAHEGBG?E?HRG*

  GRH?HKIGGPHPIHIELELILHLRIDQWLDLCAWGGGDLQHQ?L      
  GLQ?FEN-LLKBGAE??-?BNDNMLTELK?KXK?NHEADX?ACBAWMGK?

How is the array represented in MATLAB? A cell string?

[huda nawaf]

it is not necessary.

you can supposed it array of integers as

A=1 2 35 2 0 7 8 12 90 1 1 27

0 0 2 8 8 4 8 2 6 7 4 5 9 90 1 2........................8 9 0

1 2 4 7 1 0

for example , if I want to display third row, I will use

A(3,1:7)

what if I want to display the second row if I did not know the length of this row?

thanks

A(3,:)

However, it is not possible to have a numeric array that has rows of different lengths.

Depending on the data type and the needs of your program, you might be able to use some particular flag value to indicate the logical end of data in the row. For example if the flag value was 255, then you could use

t = A(3,:);

L = find(t == 255,1) - 1;

if isempty(L); L = length(t); end

t(1:L)

I am not sure what you are asking, but the below seems like a plausible answer:

a1 = cellstr(A);
fprintf('%s ', a1{:}); fprintf('\n');

Answer 2

[Dr. Seis]

If the string "A" also has end of line characters, then:

strf = strfind(A,sprintf('\n'));   
B = {''};
if ~isempty(strf)
  B = cellstr(A(1:strf(1)-1));

    if numel(strf) > 1
        for ii = 2 : numel(strf)
            B(ii) = cellstr(A(strf(ii-1)+1:strf(ii)-1));
        end
        B(ii+1) = cellstr(A(strf(ii)+1:end));
    else
        B(2) = cellstr(A(strf(1)+1:end));
    end
else
    B = cellstr(A);
end

Where "B" is now a cell array. You can access/convert any row back to a string by, for example:

row_string = char(B(some_row));

[Dr. Seis]

If your string "A" is created more like:

A = ['abc '; 'defg'; 'hi ']

A =

abc

defg

hi

then it is trivial to extract a row, just type:

deblank(A(some_row,:))

[Walter Roberson]

Of if you have done

t = cellstr(A);

then just t{some_row}

[Dr. Seis]

Ah, cool. I don't have to do this anymore:

fprintf('%s',char(t(some_row)));

Arrays cannot have different numbers of columns in each row. Maybe you're dealing with a cell array, in which case you'd just type: A{3} For an array you'd type A(3,:).

[Walter Roberson]

The posted example is characters and every line of characters is exactly the same size, with blanks to fill out to the end of the row. That is typical for character arrays: each row does actually have the same length, but it is a matter of individual program interpretation as to whether the trailing blanks in rows are meaningful or not.

[huda nawaf]

please I want know what is cell array.

can array take different cells in each row , but can not have different columns in each row

thanks
