How do i band a vector into sized brackets

I have a matrix R(i,j), where R(i,:) gives the positions of several objects at a given timestep j.
Say I have at a given timestep R(i,:) = [1 2 3 4 5 6 7] and I wish to create bands where I could collect terms say between 1-3 and 4-7.
i.e Something that would pull R(i,j) into two seperate arrays where one contains the values between 1-3 and another with the values 4-7, keeping the timesteps intact.
Can anyone think of an easy way to do this?
Thanks in advance :)

I am not certain what you are referring to.
Two possibilities:
R(i,:) = [1 2 3 4 5 6 7];
V1{i} = R(i, (R(i,:)>=1) & (R(i,:)<=3)) % Testing For Values (Cell Array)
V2{i} = R(i, (R(i,:)>=4) & (R(i,:)<=7)) % Testing For Values (Cell Array)
X1(i,:) = R(i,1:3) % Addressing Columns
X2(i,:) = R(i,4:7) % Addressing Columns
The first set test for element values within the range.
The second set simply addresses the appropriate columns. Note that you can do that with the entire matrix at once, rather than row-by-row.
