sbit stream

w= 1 0 1 
w= 0 1 1 
w= 0 1 0

how came this can be written in straight line

w= 1 0 1 0 1 1 0 1 0

Answer 1

[Walter Roberson]

You might find this easier to understand:

w = []; for i = 1:30 w = [w, A(i), B(i), C(i)]; end

Seriously :)?

[Walter Roberson]

Yup. Get it working first, and *then* optimize it.

Answer 2

[Walter Roberson]

It cannot. The first one assigns the row vector [0 1 0] to w, but the second one assigns a row vector of length 9 to w.

If your original data is a 3 x 3 matrix instead, then

w = reshape(w.',1,numel(w));

not working

[mahaveer hanuman]

those 'w' are vectors

[Walter Roberson]

What *exactly* do you have for input? And what *exactly* do you want for output?

w = 1 0 1

is not valid MATLAB input.

[mahaveer hanuman]

for i=1:30;

w=([A(i),B(i),Q(i)]);

end

after perfoming this

i got out put as

w=

1 0 1

w=

0 0 1

w=

1 1 1

and so on.........................

now i need to make them into one single bit stream

like

w=1 0 1 0 0 1 1 1 1 .....................

[Oleg Komarov]

Preallocate before the loop:

w = zeros(1,30*3);

for ...

w(i*3-2:i*3) = ([A(i),B(i),Q(i)]);

end

[Walter Roberson]

N = 30;

w = reshape([reshape(A(1:N),1,N); reshape(B(1:N),1,N); reshape(C(1:N),1,N)], 1, 3*N);

The above does not assume that A, B, or C are row vectors or column vectors. If the shapes are known and consistent, the code can be simplified -- especially if you are putting together _all_ of the vector instead of just a subset of it.

For example, if they are all row vectors and you are using all of them, then

w = [A;B;C]; w = w(:).';

thanks its working
