MATLAB: I need help preallocating array

Question

I need help making this array preallocated.

p = 10; 
newArray = [];
array = [];
for i = 1:p  
a= variable1;
b = variable2; 
c = variable3;  
d = variable4;
e = variable5;
array = [a,b,c,d,e]
newArray= [newArray array];
end

Answer 1

Look at the function "zeros".

 array = zeros(1,5);
 newArray = zeros(1,5*p);

and, in the loop

 newArray((1+(i-1)*5):(i*5))=array;

This way all you need is allocated before the loop.

I assume that the assignments of a through e come from function that have a different value for different i's.

If they are the same, it's just a tiling problem. You need "repmat".
