Hello,
In order to have a pre-specified number of observations, you use the command
a = poissrnd(b,n,m)
where 'b' is an element of the 'B' vector you specified and 'n x m' is the dimension of the number of observations.
I understand that you want to do that directly to all the elements in 'B'. You can define 'B' as a cell array and then use the 'cellfun' to apply 'poissrnd' function to each element in 'B' as follows:
B = {3, 5, 7, 9, 10}
A = cellfun(@(x) poissrnd(x,3,5),B,'UniformOutput',0)
Now element 'i' in 'A' i.e., A{i} contains '3 x 5' Poisson observations with parameter B{i}.
I hope this helps,
Ghada
