what is wrong with this simple code?

1 view (last 30 days)
Hi I am trying to create an empty array so that I can add elements to it concatenating them. This avoid the large time it takes if you dont give it a size previous the for loop, as it has to change its size at every iteration. This is the code:
>> days=double.empty(100000,1,0); m=size(days); m
for k=2:numel(UntitledCase_Temp)
m =
100000 1 0
??? Attempted to access days(1); index out of bounds because numel(days)=0.

Preallocate like this instead
days = zeros(100000,1);
