Is there a reference to this construction with NG and G in somewhere like Wikipedia or Mathworld? It would be nice to link to the wider world. –Donal Fellows 09:22, 7 February 2013 (UTC)

7 years too late: The task was written by Nigel Galloway, NG stands for NigelGalloway and G stands for Galloway. NG is a simple matrix that allows arbitrary maths, eg a "baby matrix" of {{a,b},{c,d}} just means calculate (a*x+b)/(c*x+d). Since any (but not all) of a/b/c/d can be zero we can easily write an NG that performs a simple operation such as x+1/2, or 1/x, etc. G is just the function that applies some NG to some x. --Pete Lomax (talk) 14:13, 27 August 2020 (UTC)
