this is my first post here. I'd like to know how to calculate the average array between 2 or more arrays. say i have a=[0, 1, 1, 0, 1, 0, 0] and b=[0, 0, 0, 0, 0, 1, 0].
Graph as a time series: 
What i need its an array c with the same number of elements of arrays a and b. Array c should represent the average trend of a and b. I do NOT refer to the common average (mean) of arrays' elements (value1+value2)/2, but an average of the distribution of the elements.
This is what i want:
hope you can help me :)
