Hi a question please: o1=100 o2=200 I want to write something like that:
if true
for i=randi(O1,[1 ((50/100)*O1)])
for j=randi(O2,[1 ((50/100)*O2)])
end
in fact, if
IDX=randi(O1,[1 ((50/100)*O1) and JDX=randi(O2,[1 ((50/100)*O2)])
I want to start from IDX(1):IDX(end). like:
for i=IDX(1):IDX(end)
for j=JDX(1):JDX(end)
Thank you

But I still get the error
Warning: Size vector should be a row vector with integer elements.

I do not get that. Have you possibly changed your O1 or O2 to values that are not even? Your question asked about O1=100 O2=200 both of which are even (divisible by 2).
If one of your O1 or O2 are odd, then you need to clarify whether you want the half rounded down or rounded up. For example if your O1=101 then do you want your random vector to be length 50 (101/2 rounded down) or 51 (101/2 rounded up) ?
