Hi Raul, It looks to me as if the wiki version is providing an array of shape 100 100 and it is plotting the z values for each position (x,y) within the array. You would just need to pick your parameter so that it corresponds to integer positions that would map on to the array and then insert the value of z at that position (x,y) .
At least that's is what I see happening, but believe me when I say I have been wrong before. :-) Cheers, bob On 2013-06-05, at 2:31 PM, Raul Miller wrote: > 'type surface' plot +/~2 o. i:5j99 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
