im new to matlab, does any one know , how to iterate 8 times ?

,h=[.482962913145,.836516303738,.224143868041,-1.2940952251];

convolve(h,h/2(in time));

convolve(h/2,h/4);.....up to 8 times

You could do this with a for loop, something like this

h=[.482962913145,.836516303738,.224143868041,-1.2940952251];
numIter = 8; % number of iterations
% preallocate array to hold results, one row for each convolution
R = zeros(numIter,2*length(h)-1);
for k = 1:numIter
    R(k,:) = conv(h/(2^(k-1)),h/(2^k));    
end
