Check if time equals time frame

Hello,

I'm facing the following problem.

I have a matrix A(1000x1) containing time values in terms of time steps. I want to generate a matrix which identifies the events that fit within a certain time frame with respect to the time value in that row.

Example:

A(1,1)= 50

A(2,1)= 51

A(3,1)= 52

A(4,1)= 60

A(5,1)= 61

Now I want to generate a matrix B which shows the events that occur within the time frame A(1,1):(A(1,1)+4) in the first row of matrix B. And do that for every row in A. So B should be:

B(1,:)= [2 3]

B(2,:)= [3]

B(3,:)= []

B(4,:)= [5]

B(5,:)= []

Can anyone help me with this?

B = cell(1, numel(A));
for k = 1:numel(A)
  B{k} = find(and(A > A(k), A <= A(k) + 4));
end
