I want to expand the following pattern 365 times. Have tried the repmat command, however this will produce 365 columns as well which is too big for matlab to handle.
So the end result i want is a matrix of size 86400*365,1
A = 0:28800;
B = 28801:43200;
C = 43201:46800;
D = 46801:61200;
E = 61201:86400;
x = [zeros(28800,1); 400*ones(length(B),1); zeros(length(C),1); 400*ones(length(D),1); zeros(length(E),1)];

I suggest using numel() instead of length(). The length function should be avoided because its results can be misleading when working with matrices that have more than 1 row or column.

You can give multiple dimensions to repmat:
repmat(x,1,365)
