Count Adjacent Equal Elements in a Vector
显示 更早的评论
Hey guys, I'm very new to matlab. I have been struggling to write a code that counts adjacent equal numbers in a vector and then puts all values in matrix. For example, in a vector like x = [1 3 4 5 1 5 5 4 4 4], count adjacent and equal elements. The result should be like:
yMatrix = [1 3 4 5 1 5 4
1 1 1 1 1 2 3]
回答（1 个）
dx=diff([inf,x])~=0;
yMatrix = [x(logical(dx)) ; ...
accumarray(cumsum(dx(:)),1).'],
