Re: [Jprogramming] Matrix operations questions

NB: I wrote this before looking at the J rosetta code which includes the generation of the Ybus matrix - If your object is to find the equivalent (Thevenin) resistance between any 2 points, I would suggest that it would be better to work with an admittance model. It eliminates the problem with

Thanks, Bob Re 0), we might be at cross purposes. I'd tried to point out that I hadn't seen a red dot at the top left. I forget if that's a Mac feature. 1 & 2) fine, 3) It's late here, and we're off for a fwe days tomorrow. When I can, I'll have a look at the interaction between J-ses

For those using Bob's new Jig addon, please note that as Bill pointed out, the addon directory name inadvertently used upper case, whereas lower case is required for cross platform compatibility. I should have checked this in the addon builder. I will now delete the original addon and commit a new

Thanks Jimmy, 1) I know that my coding skills aren't at the level of what you see with dissect, but if Henry is interested in the way I have approached the display, he can certainly use any of jig's ideas. Do remember that dissect is a different tool than jig and many of the decisions I made on

Hi Henry, I think that the biggest difference between jig and dissect is that jig mirrors the J text display, whereas dissect deconstructs the J sentence to give insight into the construction of the result. In short, dissect does a great deal more than jig. Jig is just an interface to the final

Thanks Ian, A great deal of the work that I did with non-visible ASCII characters was similar to your explorations with crex. One of the big challenges was the differences in the way that LF displays depending on whether it is boxed or not! I wonder as well the effect that the tty interface can

Thanks Mike, Your feed back is really appreciated, as well as your patience in running through the labs so many times to troubleshoot! I will look at chapter 4(8) and chapter 6(1). As usual I am bending the rules a little in the way that I am using PREPARE in the lab in order to generate multip

No, the brief answer is that Jsoftware does not believe that unicode identifiers are a good addition to the language. While it's certainly possible for such identifiers to become confusing if exotic characters are used, they are supported in Unbox (https://github.com/iocane/unbox, a fork of J which
