Yes, that's the way to go.  Report your problems to beta, or fix up the addon. D. is temporarily available for comparison purposes but will be removed from the release. !^:_1, which relied on D:, has been removed. Henry Rich On 9/3/2019 4:48 AM, Ben Gorte wrote: Hi, I'm trying to modify m

Mike,   Try   load'math/calculus'   +: deriv_jcalculus_ 1 This is the 'comparable replacement' you asked for. Documentation?  No, no more than with d. D. D: - except that now you can look at the source in J.  There are 3 modifiers: deriv_jcalculus_ (replacing d.), pderiv_jcalculus_ (D.), ssl

Re: [Jprogramming] Calculus primitives are removed

Backwards compatibility is important, but not the only consideration. 1. Calculus had more outstanding crashes and errors on the bug list than any other component. 2. Here the good was the enemy of the best.  We have long wanted to move calculus into an addon, but nobody would ever work on it

Re: [Jprogramming] Calculus primitives are removed

Addons and labs need to change to use cover adverb and I think it will work even better than before because D. can be enhanced much easier if it is implemented in J scripts. On Tue, Aug 27, 2019, 9:08 AM Ben Gorte wrote: > Good morning, > > I was in a Geodesy department for many years and am s

Good morning, I was in a Geodesy department for many years and am still doing those kind of things. Geodesists are the well-known masters of least-squares adjustment, but not being a geodesist myself, most of my career is based on the Best Fit lab, notably on the (in)famous adverb: Nwtn =: adverb

Re: [Jprogramming] Calculus primitives are removed

I have mixed feelings about this. I know d. and D. are not used very often, but this is going to break some code, i.e. break backwards compatibility. I have some code that uses d./D. Is backwards compatibility not considered an important point? On Tuesday, August 27, 2019, 8:48:04 AM GMT+

Look at the addon.  If you want to improve it, ask for permission to modify it.  People have talked about doing this from time to time, and now it's possible.  Calculus is looking for a champion. Henry Rich On 8/26/2019 7:15 PM, Raul Miller wrote: On Mon, Aug 26, 2019 at 7:05 PM Henry Rich w

[Jprogramming] Calculus primitives are removed

J has supported symbolic differentiation and integration for some time.  Starting with Release 9.01, primitive support for calculus is withdrawn. The calculus primitives were a proof-of-concept that was an incomplete success.  They worked, but they were not complete, and the nature of mathemat
