lets say i have an array with periodic set of elements such as below:
A=[2 2 2 3 3 4 4 5 5 5 1 1 1 2 2 2 2 3 3 4 4 4 4 5 5 1 1 2 3 3 4 4 4 5 5];
i want to split Array A in to 3 separate arrays(in this case) as it reach to element 5 as below:
B1=[2 2 2 3 3 4 4 5 5 5];
B2=[1 1 1 2 2 2 2 3 3 4 4 4 4 5 5];
B3=[1 1 2 3 3 4 4 4 5 5];
i greatly appreciate your help
thank you

B = mat2cell(A(:)',1,diff(find([true,diff([A(:)'== 5,0]) == -1])));

Please attach your array A with size [32025 x 1] as mat-file.

A=[2 2 2 3 3 4 4 5 5 5 1 1 1 2 2 2 2 3 3 4 4 4 4 5 5 1 1 2 3 3 4 4 4 5 5];
didx = diff(A==5) ;
idx = find(didx==-1) ;
idx = [0 idx length(A)] ;
N = length(idx)-1 ;
iwant = cell(N,1) ;
for i = 1:N
iwant{i} = A(idx(i)+1:idx(i+1)) ;
end
