如何在netlogo中列出累计金额 [英] How make a list of cumulative sum in netlogo

问题描述

如何列出另一个列表的累加总和?

我尝试过这种方式:

;;all temperatrue-values around the turtle saved in list 
set temperature_values (list [(output-heat + 1)^ Freedom] of neighbors) 


;;build cumulative value of temperatures and put each value in list 
let tempsum 0 
set tempsum_list [] 
foreach temperature_values 
[set tempsum (tempsum + ? ) 
set tempsum_list fput tempsum tempsum_list 

] 

但是它不起作用.谁能解决这个问题?它说"+排除了输入，但获得了列表".

解决方案

your code for a cumulative sum works (except that I think you need lput rather than fput. You can see it with this:

to test
  let ll [1 2 3 4] 
  let tempsum 0 
  let tempsum_list [] 
  foreach ll 
  [ set tempsum (tempsum + ? ) 
    set tempsum_list lput tempsum tempsum_list 
  ]
  print tempsum_list
end

Did the error highlight the line set temperature_values (list [(output-heat + 1)^ Freedom] of neighbors)? Try putting a space after between ) and ^. NetLogo is picky about space around mathematical operators.
