special sorting
显示 更早的评论
special sorting! i have the input vector of flags for different segments of the vector (flags are distributed randomly). how can i sort it to get the output? basically it reads from the beginning of the vector and labels each segment of the vector consecutively. there is no repetitive flags in the input vector for different segments.
input = [2 2, 5, 6 6 6, 1 1 1 1, 4, 3 3]
output= [1 1, 2, 3 3 3, 4 4 4 4, 5, 6 6]

Sorry but I can't understand, you show the flags (input) and the output but no original vector to be sorted

Do not use "input" as name of a variable, because it is a name of a built-in function.
in = [2, 2, 5, 6, 6, 6, 1, 1, 1, 1, 4, 3, 3];
out = cumsum([1, diff(a) ~= 0]);
>> out = [1 1, 2, 3, 3, 3, 4, 4, 4, 4, 5, 6, 6]
