I am learning mathematica fast, but this question has me stumped for sure! List={{"a", 1, 14}, {"a", 2, 15}, {"a", 3,16}, {"a", 4, 17}, {"a", 5, 18},{"a",5,19}} element={"a", 1, 14} position1="a" position2=1 position3=14 I want to take moving average of position3 and then divide position3 by the dividing the moving average x units forward. for example, lets say... length of moving average= 3 offset division= 2 and lets just look at position 3 for clarity. {14,15,16,17,18,19} moving average=> {15,16,17,18} offset division=> {18/15,19/16} so since the moving average is 3, two units are automatically taken off the beginning of the moving average list. and since the division needs to offset 2 units forward, this makes the final list smaller yet. so then my final list needs to be cut down as well final result: add another position for the movingaverage/offsetdivision {{"a", 5, 18,18/15},{"a",5,19,19/16}} I need this function to work for a moving average of x units and an offset division of y units URL: ,
