Hello everyone,
Using vectorization, I want to merge the sequences. Let say I have vector v with values
v = [43 43 43 33 34 35 35 43 43 43 43 43];
I want to get an other vector which should store on only
ind =[1 4 5 6 8];
The sequence should be eleminated and their index should be safed in ind.

ind = [1 find(diff(v) ~= 0)+1];

ind=find(diff([v(1)+1 v]))
