Calculate with different sized matrixes

Hi, im new to MatLab

i have two matrixes with different sizes. One is 36832x1(A) and the other is 931029x1(B).

I have to devide the A through B. I tried to shorten B through calculating averages, but it is very difficult to get the same length as A as result.

Maybe someone has a small hint because I think im only missing a key word for finding the correct solution.

Thanks

A = randi(9,1,10) % a short vector

A = 1×10

8 3 1 7 1 6 1 8 7 8

B = randi(9,1,17) % a long vector

B = 1×17

4 9 5 8 4 1 7 2 4 6 4 1 6 4 6 5 5

% interpolate to shorten the long vector
Bs = interp1(1:numel(B),B,linspace(1,numel(B),numel(A)),'linear')

Bs = 1×10

4.0000 5.8889 5.7778 3.0000 2.2222 5.7778 2.0000 5.1111 5.7778 5.0000

C = A./Bs % divide or something

C = 1×10

2.0000 0.5094 0.1731 2.3333 0.4500 1.0385 0.5000 1.5652 1.2115 1.6000
