Eliminate or merge the sequences

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]))
