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
C = 1×5 cell array
{[1 2 3]} {[6 7 8]} {[11 12 13 14 15]} {[17 18 19]} {[30 31 32]}
NC
NC = 1×4 cell array
{[3 6]} {[8 11]} {[15 17]} {[19 30]}

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
C = 1×5 cell array
{[1 2 3]} {[6 7 8]} {[11 12 13 14 15]} {[17 18 19]} {[30 31 32]}
NC
NC = 1×4 cell array
{[3 6]} {[8 11]} {[15 17]} {[19 30]}

Yep nice thanks for answering .
What if i wanted to apply the same code in a datetime matrix?
For example
A = ['29-May-2017 00:02:00' '29-May-2017 00:03:00' '29-May-2017 00:04:00' '29-May-2017 00:08:00'...
'29-May-2017 00:09:00' '29-May-2017 00:010:00' '29-May-2017 00:11:00' '29-May-2017 00:14:00']
so as to find when the time values are non consequtive and also plot them like before.
i thinks its kinda trickier,but any comments would be helpfull.

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

Do you know what else i need do add in this code, so as to store the order that each value has in the Matrix A ?
Because i also want to plot the consequtive/non consequtive values in the same figure but with different color,but in the right order.
