my solution would be:
vlen=randi(10,[10,1])
V=arrayfun(@(x) (mod(x,2)*ones(x,1)),vlen,'UniformOutput',false)
Now the codes that you asked:
rand generates a random number between 0 and 1. multiplying by 10 result into a random number between 0 and 10. floor rounds it down so 9.85 becomes 9. so floor(rand*10) generates a number between 0 and 9; hence adding 1 to generate a random number between 1 and 10.
ones (1, Vlen) generates a vector of length Vlen and all elements being one rem(Vlen,2) gives 0 if Vlen is even and gives 1 if Vlen is odd. So that line generates a vector of length Vlen and all the elements would be 1 if Vlen is odd;otherwise, the elements would be 0.
The two line code that I give you at the beginning would do the same thing.
vlen=randi(10,[10,1]) generates 10 random number between 1 and 10.
arrayfun applies (mod(x,2)*ones(x,1)) on each element of Vlen, with x being each element of glen. mod(x,2) again is zero if x is even and it is one if x is odd and ones(x,1) generates a vector of length x.
