H_Mat=[1, 0, 1, 0, 1, 0, 1, 0;
1, 0, 0, 1, 0, 1, 0, 1;
0, 1, 1, 0, 0, 1, 1, 0;
0, 1, 0, 1, 1, 0, 0, 1];
[row,coloumn]=size(H_Mat);
for i = 1:row
for j = 1:coloumn
fprintf (' %d,', H_Mat (i,j));

Try:
H_Mat=[1, 0, 1, 0, 1, 0, 1, 0; 1, 0, 0, 1, 0, 1, 0, 1; 0, 1, 1, 0, 0, 1, 1, 0; 0, 1, 0, 1, 1, 0, 0, 1];
dlmwrite('test1.txt', H_Mat,'delimiter',' ')

Perhaps you just need to swap the order of rows and columns in the for loops, and add a new line:
for j = 1:row
for i = 1:coloumn
fprintf (' %d,', H_Mat (j,i));
end
fprintf ('\n');
end
In the command window:
1, 0, 1, 0, 1, 0, 1, 0,
1, 0, 0, 1, 0, 1, 0, 1,
0, 1, 1, 0, 0, 1, 1, 0,
0, 1, 0, 1, 1, 0, 0, 1,

The colon, when used where you'd normally use an index, means "all". So in your case, where the colon is in the first index, which corresponds to the "rows" index, the colon mean "all rows". So X(:,p) means "all rows in column #p." Basically it extracts out the pth column from the matrix into a vertical column vector.
