Hi ! How can I 'join vector C and signal to get a matrix?
I've tried like this but I dont know if its okay.
Thanks in advance.
f_sine=3e6; % sine frequency [Hz]
T1=1/f_sine; % sine period
n=5; % number of periods
tt=n*T1;
t1 = 0:dt:tt-dt;
burst=sin(2*pi*f_sine*t1);
ww1=hanning(length(burst)/2);
ww=[ww1;zeros(length(burst)/2,1)];
signal=burst.*ww';
iterations=30000;
C = zeros(1, iterations-numel(signal));
v = [signal, C]';

Hi mm99,
your code snippet is not executable. "dt" and "N" are not given. As far as I see, "signal" is a vector whereas "vector" is a matrix. I guess, matrix dimensions and vector do not match, thus joining them is not possible. Provide executable code, and somebody will figure out how to match your variable sizes.
Kind regards,
Robert

Depends on whether signal is a column vector or row vector
If it's a column vector you probably want to add a column of zeros to the right of signal:
v = [signal zeros( size(signal,1),1 )].' % note the matrix is transposed as you wrote in the original code
If its a row vector you could add zeros below singal as follows:
v = [signal; zeros( 1,size(signal,2) )].'

Ok, I see what you are asking.
v = zeros(1,iterations);
v(1:numel(signal))=signal;
