How to split A vector as increasing and decreasing vectors. eg.
A=[1 1 2 2 3 3 8 9 4 3 2 2 2 1 0]
I want the output to be two vectors.
First should be the increasing one
[1 1 2 2 3 3 8 9]
Second should be the decreasing one
[4 3 2 2 2 1 0]
I have tried diff(), but the problem is with the repeating numbers which comes in between of increasing sequencce.

A=[1 1 2 2 3 3 8 9 4 3 2 2 2 1 0];
idx=find(diff(A)<0,1);%only get the first value
part1=A(1:idx);
part2=A((idx+1):end);
