Is there any way that this could be replicated? I've been using solved symbolically and FindRoot but if there is another intuitive go around would be appreciated. Yellow marked were initial values for finding the roots.  Thanks in advance~ Edited by user 15 January 2024 16:13:54(UTC)

There is Mathcad Block similar to this. Here is the answer to your question. Actually there is no intuitive here, it is just habits. FindRoot(), roots(), solve(), al_nleqsolve(), etc are easier to me. Because I am more used to work with them. You possibly will be more comfortable to use Mathcad Block. Because you used Given,Find functions for long. Regards  mathcad_block.sm (7kb) downloaded 14 time(s).

Well first of all I thank you for your reply. I pretty much know about the FindRoot(), roots(), and solve() from practicing with mathematics problem, but I don't know if I missed out but I haven't encountered this al_nleqsolve(). Would you demonstrate how this works? Also, one big thing. I don't know how the Mathcad block works. I can't recreate what you did. Like I said I can do this with the FindRoot() but I'm pretty much looking for another way to present/solve it. I kinda like the way it turned out in the way you do it but I can't seem to recreate it with my smath. Thanks. Originally Posted by: overlord  There is Mathcad Block similar to this.

Usually it is more capable to solve some equations. Where all other fails this one can solve probably. But it is different, cumbersome, take some space. Generally last resort for me before maple/maxima. There is also jacobi matrix option. Picture on the right is screenshot from Reference book. al_nleqsolve_examples.sm (11kb) downloaded 15 time(s).

Its requirements works similar to FindRoot() or other solvers. When you add block and click on it a blueish rectangle area appears. Your unknown functions has to be inside of that area. And you need to write your solver with start points/guesses to its handler. Here let me show it with a gif explains on your question. More info can be found in Extensions page link below. Mathcad Block has very detailed examples on its own page. https://en.smath.com/forum/yaf_postst726_Mathcad-Toolbox.aspx Edited by user 06 January 2024 15:39:46(UTC)

I have a few more questions for another thread I guess, but I'll try here first. I don't know if I you'll see this but I'll try anyway. (1) Where does that cream-colored rounded rectangles come from? Is that a text region, a special function? I tried to replicate that days ago but I went blank how to. (2) May you look at the image below. I generally use: [text goes here, variable:=1mm] all in the same line and it comes blank. This was not available in Mathcad and was actually a good thing for me since I possibly can't misplace their descriptors whenever I'm moving things,especially variable, around. Problem is this one makes an error for me. Is what I'm doing a bad practice? I'm trying out and contemplating on migrating from Mathcad to SMath so forgive me for being a little bit ignorant.   Thanks

Yellow marked were initial values for finding the roots. Commonly, plugins solvers fail. in lieu, you rescue via: 1. root Dichotomy for single/multiple roots. 2. solve Xsecant for single/multiple intersections. As you wish, attach your original document for inspection Jean

Those are description text. Right click to math/plot/table rehion and you will see an option from that menu. Originally Posted by: GFDIntano (2) Is what I'm doing a bad practice? İt is all up to you. Don't think it as bad or good. There are sheets you activate description and it is enough. And there are some you put text region. İt depends on visual aestethics of that particular sheet. By the way, SMath is similar but not same to Mathcad. Don't expect 100% conversion. But you can do everything on SMath as done on Mathcad. One way or another. Regards

I installed the plugin for some time, but I was looking at it "like the calf at the new gate". This is a Romanian expression, translated word for word, which means that I did not understand at all how to use this "mathcad block". I would also like to find out at the same time, which function in SMath fits best with the "Given - Minerr" combination in Mathcad, to be used effectively together with the newly introduced mathcad block in SMath. For example, I have a system with a lot of equations with 6 unknowns (a lot meaning over 300) which I managed to solve in Mathcad by the "Given - Minerr" procedure (using the Levenberg-Marquard method) but which I am struggling with useless for a good chunk of time to solve it in SMath as well. Where could I find bibliographic references about solving such cases?! Similarly, I don't know how to use the new "table" plugin, probably also coming from Mathcad. Maybe someone can explain it to me. Greetings Edited by user 21 April 2024 12:00:23(UTC)
