I have two arrays with same dimension:
a1 = [1,1,3,4,6,6] a2 = [1,2,3,4,5,6]
But I want to group both of them with respect to array
a1 and get the mean of the array
a2 for each group.
My output is coming from array
a2, as mentioned below:
result: 1.5 3.0 4.0 5.5
Please suggest an approach to achieve this task.
