normsum#

class normsum(arr, total=None)[source]#

Multiply a list or array by some normalizing factor so that its sum is equal to the total. Formerly called “scaleratio”.

Parameters:
  • arr (array) – array (or list) to normalize

  • total (float) – amount to sum to (default 1)

Example:

normarr = sc.normsum([2,5,3,10], 100) # Scale so sum equals 100; returns [10.0, 25.0, 15.0, 50.0]
