OK guys, lets say i have a matrix A=[1,2,3,6,7,8,11,12,13,14,15,17,18,19,30,31,32] , i want to locate the consequtive numbers and store them in matrices ,and also the the values that are not consequtive and store them in different matrices.So the output should be like:
A1=[1 2 3] B1=[3 6]
A2=[6 7 8 ] B2=[8 11]
A3 = [11 12 13 14 15 ] B3 = [15 17]
A4=[17 18 19 ] B4=[19 30]
A5=[ 30 31 32]
Any idea how can i solve this?

Hi. You can try this:
A = [1,2,3,6,7,8,11,12,13,14,15,17,18,19,30,31,32];
C = {} ; NC = {}; % Consecutive / Non Consecutive vectors
ind = find(diff(A)~=1);
for n = 1 : numel(ind), NC{n} = A(ind(n):ind(n)+1) ; end
ind = [1 ind+1 numel(A)+1];
for n = 1 : numel(ind)-1, C{n} = A(ind(n):ind(n+1)-1) ; end
C
NC

You mean, like that?
A = [1,2,3,6,7,8,11,12,13,14,15,17,18,19,30,31,32];
C = {} ; NC = {}; % Consecutive / Non Consecutive vectors
figure
ind = find(diff(A)~=1);
for n = 1 : numel(ind)
NC{n} = A(ind(n):ind(n)+1);
plot(ind(n):ind(n)+1, NC{n}, 'r') ; hold on;
end
ind = [1 ind+1 numel(A)+1];
for n = 1 : numel(ind)-1
C{n} = A(ind(n):ind(n+1)-1);
plot(ind(n):ind(n+1)-1, C{n}, 'b');
end
C

A=[1,2,3,6,7,8,11,12,13,14,15,17,18,19,30,31,32];
a=diff(A);
n=num2str(a==1);nn=num2str(a~=1);
n=n(n~=' ');nn=nn(nn~=' ');
[s,e]=regexp(n,'[1]+');
[ss,ee]=regexp(nn,'[1]+');
for k=1:length(s)
AA{k}=A(s(k):e(k)+1);
end
for k=1:length(ss)
BB{k}=A(ss(k):ee(k)+1);
end
