matlab - How to create two or more matrices from a single one under certain conditions? -

hello new in matlab , cannot figure out how solve problem.

i have matrix1:

1   0 2   334.456 3   654.7654 4   65.76543 1   0 2   543.43567 3   98.432 4   54.9876 5   12.456 

and matrix2:

1   2 2   3 3   4 1   2 2   3 3   4 4   5 

matrix2 represents links found in matrix1 in order appear.

i separate links in blocks (matrices) each block starts stop 1. analysing matrix2 should produce 2 new matrices 1 links (1,2)(2,3)(3,4) , other links (1,2)(2,3)(3,4)(4,5). each time find stop 1, starts building new matrix.
a , b come out as:

a= [1,2, 334.456; 2,3,654.7654;3,4,65.76543] b=[1,2,543.43567;2,3,98.432;3,4,54.9876;4,5,12.456] 

i think want. matrices cell array containing amount of distinct matrices required (based on amount of 1's in column 1 of matrix2).

matrix1=[1 0; 2   334.456;3   654.7654;4   65.76543;1   0;2   543.43567;3   98.432;4   54.9876;5   12.456]; matrix2=[1   2; 2   3; 3   4; 1   2; 2   3; 3   4; 4   5];  rows=find(matrix2(:,1)==1); % find row numbers 1 in column 1 of matrix 2) rows=[rows(2:end); size(matrix2,1)+1]; % ignore (obvious) first row, add end of matrix2 nrows=size(rows,1);  matrices=cell(nrows,1); i=1:nrows     lb=1;     if i>1         lb=rows(i-1);     end     matrices{i,1}=zeros(rows(i)-lb,3);     j=lb:rows(i)-1         matrices{i,1}(j-lb+1,:)=[matrix2(j,:), matrix1(lb+matrix2(j,2)-2+i,2)];     end end 

with following result:

>> matrices{1,1}  ans =      1.0000    2.0000  334.4560     2.0000    3.0000  654.7654     3.0000    4.0000   65.7654  >> matrices{2,1}  ans =      1.0000    2.0000  543.4357     2.0000    3.0000   98.4320     3.0000    4.0000   54.9876     4.0000    5.0000   12.4560
