I don't understand the question. You want to convert a vector with 45'000 elements to one with 36'000 elements? What does that mean? I suppose you don't want to delete 9'000 elements?

This is what I wanted...Thank you guys
a=resample(b, 45001,36001);

vect_45 = rand(1,45000); % your 1x45000 array
vect_36 = vect_45(:,1:36000);
vect_27 = rand(1,27000); % your 1x27000 array
vect_36_b = [vect_27 zeros(1,9000)]; % you have to add elements to fill the gaps between 27000 and 36000, I added zeros
