Write data .txt format with different vector in different column

I have two different single column matrix

A = [1 2 3 4 5 6 7]; B = [110 120 114 116 117 119 121];

I want to write it in the .txt format as shown below,

1  110 
2  120
3  114
4  116
5  117
6  119
7  121

Now I am try to do it with the below mentioned code but I am getting all the data in a single column,

fid=fopen('MyFile.txt','wt');
        fprintf(fid,'%d\r\n',A);
    fprintf(fid,'%d\r\n',B);
    fclose(fid);

A = [A B];  
fid=fopen('MyFile.txt','wt');
for i = 1:length(A)
    fprintf(fid,'%d %d\n',A(i,1),A(i,2));
end
fclose(fid);

Hi Mridul, Tried the above code it is giving the below error

Index exceeds matrix dimensions.

    Error in del2 (line 6)
        fprintf(fid,'%d %d\n',A(i,1),A(i,2));

I think Mridul assumed that A and B were column vectors as you've stated whereas you've got row vectors. So instead of creating a Nx2 matrix, [A B] creates a row vector. That can easily be fixed with

 A = [A; B];

and iterating over the columns instead of rows.

But it's also a waste of time. You don't need a loop.

@Mridul, note that length should never be used on a matrix. Always use size with an explicit dimension.

Thanks works as required..

A loop is a waste of time:

fid = fopen('MyFile.txt', 'wt');
fprintf(fid, '%d %d\n', [A; B]);
fclose(fid);

This assumes that A and B are row vectors as you've shown but not as you've stated. A and B must of course have the same number of elements.

I assumeed you wanted a space between each column.

+1 no loop is the way to go.

Thanks Guillaume, Yes you assumed correct, I want space between each column.
