For example, i have
x = [0 0 0 1 1 0 0 0 1 0 1 0]
I want the index of the first zero or one, but not the duplicates.
So the vector should become:
0 1 0 1 0 1 0
Where the indices would be '1 4 6 9 10 11 12'
Thanks

>> x = [0,0,0,1,1,0,0,0,1,0,1,0];
>> idx = [1,1+find(diff(x)~=0)]
idx =
1 4 6 9 10 11 12
>> vec = x(idx)
vec =
0 1 0 1 0 1 0

Or with https://www.mathworks.com/matlabcentral/fileexchange/41813-runlength:
x = [0 0 0 1 1 0 0 0 1 0 1 0]
[B, N, Index] = RunLength(x)
Then B contains the unique values and Index the indices.
