MergeSelectedRows Operator.
|
|
|
|
MergeSelectedRows is used to merge the duplicated rows of the input. The
|
|
output's row has no duplicated, and it's order is incremental.
|
|
|
|
Example:
|
|
Input:
|
|
X.rows is [0, 5, 5, 4, 19]
|
|
X.height is 20
|
|
X.value is:
|
|
[[1, 1]
|
|
[2, 2]
|
|
[3, 3]
|
|
[4, 4]
|
|
[6, 6]]
|
|
|
|
Output:
|
|
Out.row is [0, 4, 5, 19]
|
|
Out.height is 20
|
|
Out.value is:
|
|
[[1, 1]
|
|
[4, 4]
|
|
[5, 5]
|
|
[6, 6]]
