x = [1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 3 3 ];
indexes = [1 find(x(2:end) - x(1:end-1))+1 numel(x)];
indexes = floor(movmean(indexes, 2, 'Endpoints', 'discard'));

val=unique(A);
iC=arrayfun(@(x) median(find(A==x)),val);
for your A above
>> val=unique(A);
>> iC=arrayfun(@(x) median(find(A==x)),val)
iC =
3 8 14
