MATLAB: Is there a quick and easy way to insert/delete values into the middle or beginning of a cell array and/or a numerical array

insert into arraysinsert into cell arrays

I have a cell array and a numerical array. I want to insert values into the beggining, middle and end of the cell array or the numerical array. Is there an easy way to do this.
I also want to be able to delete array elements at the beginning, middle or end of the arrays. Same question…

Just use indexing:
>> V = randperm(9)
V =
   9   5   7   3   4   6   8   2   1
>> idx = 3;
>> val = 0;
>> V = [V(1:idx),val,V(idx+1:end)]
V =
   9   5   7   0   3   4   6   8   2   1
Note that this will work for the beginning and end too (try it with idx=0).
