Let's say I have matrix A=[1; 2 ;3; 6; 7 ;8 ;11 ;12 ;13]
I need a script which goes through matrix A one by one and defines the elements which A(k+1)-A(k)>1
then I need that elements to be saved in matrix B
so B=[6; 11]

B=A([false;diff(A)>1])

thanks.
do you know hiw we can solve it with a for loop?
when I use the following code, it saves the elements in matrix B on top of each other and matrix B shows only one element. which is B=[11]. any solution for that?
B=[];
for k=1:length(A)-1
if A(k+1)-A(k)>1
B=A(k+1);
end
end
