Given that: S =: ( x : x^2 = 9) what is S
S is 3 -3 This can easily be done in your head. How would one write J code that would do this? On a more complicated note, how could one write in J code that would do: S = ( x : (x^2)-2 = 0) In this case S is 2^0.5 and _2^0.5 The general question is: How does one write J code to determine a set based on a system of one or more equations? Any thoughts on this would be appreciated. thanks ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
