how can i call up either part of the results like (e1,e5,e6,e9)or (from e1 to e7)? then i need to combin them in one array

if i have a lot of arrays with different dimensions and their names take the following forms :e1,e2,e3,...,e10 and so on. how can i call up either part of the results like (e1,e5,e6,e9)or (from e1 to e7)? then i need to combine them in one array . for your information , these array names resulted from this code :

a=[1:10];
c=length(a)
for k=1:10;
  if (k<c)
  b{k}=nchoosek(a,k)
  end
end

I'm assuming that the results e1, e2, e3... in the code you wrote is b{k}... you might get your results as an numeric array or as a cell array

Array form: Results 1 to 4

myArray = [b{1:4}]

Cell form: Results 7 to 2

myCell = b{7:-1:2}

Array form: Results 4 to last

myArray = [b{4:end}]

Cell form: Results 3, 6 and 2

myCell = b{[3,6,2]}

Array form: Every other result

myArray = [b{1:2:end}]
