Editing a matrix to a text file

I have a matrix that is saved to a text file. The output of that code is a matrix which looks something like below:

• 0000000000
• 0000000000
• 0000000000
• 0000000000

How can I create a space between each element so that it looks something like this:

• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0
• 0 0 0 0 0 0 0 0 0 0

The code that I am using is the following:

im1 = imread('im10.png');

bw1 = im2bw(im1, 0.5);

fileID = fopen('exp1.txt','wt'); %open for writing

for i=1:size(bw1,1)

    fprintf(fileID,'%d', bw1(i,:))

    fprintf(fileID, '\n')
end
fclose(fileID)

The code is used to change a photo to a binary and save it as 1s and 0s. The only thing I would like to do is have one space between each element in each row.

Thank you very much

Can't you just add a space to the fprintf?:

fprintf(fileID,'%d ', bw1(i,:))
