If i have a matrix A=[ 1 2 3, 4 5 6, 7 8 9, 0 0 0, 0 0 0, 10 11 12, 13 14 15, 0 0 0, 0 0 0, 16 17 18 upto 10000 points]
here 1 2 3 are coordinates x y z .
so I want to store data in such a way that when we find two rows of all zeros there should be a new matrix created.
we need output like:
B1=[1 2 3, 4 5 6, 7 8 9]
B2=[10 11 12, 13 14 15]
B3=[16 17 18, .....]
B4= so on... upto last point of A.

If you have Image Processing Toolbox, how about the following?
% Sample data
A = [...
1 2 3;...
4 5 6;...
7 8 9;...
0 0 0;...
0 0 0;...
10 11 12;...
13 14 15;...
0 0 0;...
0 0 0;...
16 17 18];
% Create label array
idx = ~all(A==0,2);
label = bwlabel(idx);
% Split the matrix A based on the label
c = splitapply(@(x){x}, A(idx,:), label(idx));
In this case, c{1}, c{2},....,c{N} corresponds to your desired mabrix B1, B2,...,BN.
