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,

I got it now, thanks :)

hey can you please explain me what does this expression mean? W = X(:,p);

the original situation where i use this one is

function Y = SecondStage(H_Mat,V,X,Z)

Y = zeros(size(H_Mat)); for q = 1:4 for p = 1:8 W = X(:,p); W(q)=[]; W = sum(W); %update every node through variables. Y(q,p)=H_Mat(q,p)*(V(p)+W); end end
