Sorry, bit of a newbie question here, I'll try an be as clear as I can (1&o. * 2&o.) d. 1 (2&o. * 2&o.) + 1&o. * -@(1&o.) NB. Great, no problems so far
sincos =. (1&o. * 2&o.) sincos d. 1 sincos d.1 NB. Hm.... What can I do to the "sincos" verb so that it is presented to the d. adverb in terms of its primitives so that the differentiation can take place? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
