I am interested to know what it would take to implement solve block functionality into SMath. This is the one feature I feel sets MatchCad apart from SMath. Are others wanting this feature? Would it help if we were all to pony up and donate to the cause? Could we make this into a Kickstarter project? Let me know your thoughts on this. Thanks.

Regarding your comment, I remembered some of my first post on this Forum - it was long time ago. Read it please and have some fun. I was a bit younger and Andrey had much more time at that time

Matcad <-> SMath ...

You may give the Maxima plugin a try. It has as symbolic solve function - Solve(). For numeric problems, the function FindRoot() from the plugin NonlinearSolvers is very useful.

By the way Martin,

I might missed it, but I think there is still no answer about the differences between the official (wrong) and unofficial-portable (correct) and FindRoot() example

Can't reproduce this. Based on 0.97.5189 there is no difference between portable and non-portable version.

This is quite strange

. Could someone else else try to reproduce this please.
This is only happening to me with the official (regular) install

I confirm version 1.0.9999.5 according to plugin dir name. I also tried to change arg/dec sep settings to komma/period and get the same (correct) result.

Hello Davide,

I also confirm the plugin version - see the picture please.
BTW, this is the same on my both computers home-Win7 32bit, office-Win7 64bit

I hate to be such a newbie and ask stupid questions but how do I go about installing the "Nonlinear Solvers" plugin? I tried this and got a request for a password. That seemed very strange to me. I am using build 4909 on Linux.

Also, I discovered that I can solve this system of equations using the "roots" function but I had to do it without units. Is this a reason to use the FindRoots method or am I just using the roots method wrong? BTW, I stumbled across the other real solution of d=2.292 and h=0.242.

I am SO much more proficient with MathCad (version 6.0+) and this frustrates me right now. I hope to be comfortable with SMath soon but it will take a bit. Once I am I plan to teach a class at my work on how to solve problems using SMath. Thanks for your help.

There are no stupid questions... In the Extensions Manager (EM) some plugins are protected by passwords because are new (potentially unstable) or under development. You may find the most of them in the Extensions section of the forum. About Nonlinear Solvers here there is the official thread (and the first post contains the password).

roots/solve are really powerful but units are not supported; this is just one of the things behind the development of the plugin (BTW more or less all the algorithms of this plugin are available also as worksheets).
