help with preallocating matrix ?

I want to preallocate a matrix a dynamic matrix Archive[M,6], The size of our matrix limited by 200. At beggening M=1 then add elements to Archive by using the following function:

function Add ( Archive, Solution)

while( size(Archive,1) <= 200 )

Archive=[Archive;Solution]

end

end

where solution is Solution[1,6].

How preallocate the Archive matrix ?

If it is are fixed,can consider the extra zeros (If generated data are not sufficients to allocate all)

Archive=zeros(1,200);

Without knowing the size of the data? you may do following way

Archive=[];

Still it not perfect as preallocate with specific size. More, check with the Elapsed time, to see the time difference of execution.

@KALYAN ACHARJYA thank you for answer, but I won't zeros

Are there another methods ? because I wille added [0,0,0,0,0,0,,0] as a soulution so I dont want to use this method.
