How can I create a vector of number names
for example,
v= ["λ1","λ2".... ,"λn"]
so i can get a vector v= ["λ1","λ2","λ3","λ4","λ5","λ6","λ7","λ8"]
as i want to use it in table .....'RowNames',v)
The n value wanted to be changed so the question again how to number the name based on n

You actually can:
>> v = ["λ1","λ2","λ3"]
v =
1×3 string array
"λ1" "λ2" "λ3"
>> t = table([1;2;3],'RowNames',v)
t =
3×1 table
λ1 1
λ2 2
λ3 3
>> t('λ3',:)
ans =
λ3 3
Originally, variable names had to be valid MATLAB identifiers, but now even those can have arbitrary characters. With variable names and dot indexing, you can't write t.λ3, you need to write something like t.('λ3'). But with row names there's no dot indexing, you always have to put row names in quotes like t('RowName',:). So there's not really a reason to limit row names to valid identifiers.
