How to get a geometric sequence?

Hi, I have
tao=1000;
v=0.9;
T1=0.01;
I want to have a geometric sequence T, where T1=T2=T3...=T1000 ( since tao=1000)
The first 100 T will be equal to T1,
The second 100 T which starts from T101 until T200= v*T1
The third 100 T ( from T201 until T300 = v*v*T1)
The fourth 100 T (from T301 till T400 = v*v*v*T1)
and so on.
How am I going to get the sequence? Thanks in advance.

Use the .^ operator and matrix multiplication
T = v.^(0:9) * T1;
T = ones(100,1)*T;
T = T(:);
Alternatively (maybe faster)
T = v.^(0:9) * T1;
T = T(ones(1,100), :);
T = T(:);

It was not perfectly clear to me what you needed to leave as a variable, and what is a constant. But, this should get you started.
v=0.9;
T1=0.01;
T = T1*ones(100,10);
v_vector = v.^(0:9);
T = bsxfun(@times,T,v_vector)
T = reshape(T,1,1000)
