Good afternoon community, I ran into a problem. It turns out that I want to solve some equations whose data are found as matrices and I want to calculate the unknowns for each row of said matrix, but at the same time there are certain conditions that I want to be met to determine those unknowns. Thanks for your attention. Mathcad Prime V.9.0

Buenas tardes comunidad, me encontré con un problema. Resulta que deseo resolver unas ecuaciones cuyos datos se encuentran como matrices y deseo calcular las incógnitas para cada fila de dicha matriz, pero a la vez hay ciertas condiciones que quiero que se cumpla para determinar esas incógnitas. Gracias por la atención. Mathcad Prime V.9.0

After turning the solve block into a function you could use it the following way to create the table you seem to be looking for.

It seems you have a few wrong alpha values in your Resultado table. I added the input values Mx,My and Ps to that table for completeness

or a slightly different way

EDIT: When I started this post, Terry had not yet posted his table creation variant. Obviously it took me too long to press the "Post" button 😉

Hi Ycarlos

Parametric Solve is the solution

    A disease of our times, I'm afraid, Werner.

     

    I have a very long-standing request for forum application developers to implement a Post button that posts my reply when I start typing as opposed to when I finish playing around with my code and message.  And I've got an even longer-standing request for a button that applies edits to a post before the original post is posted - that would have saved me a lot of embarrassment over the years. Is it too much to ask that the software minions come up with a retro-causal button? 👿

     

    I mean, H G Wells invented the Time Machine in 1895 (well, OK, The Time Traveller did) and the BBC have had the Tardis since 1963 (sigh, all right, The Doctor had it.  I do wish people wouldn't be so pedantic.  🙄).  What are CERN using all their money for if not something practicable?  I might have to write a stiff letter of complaint to The Times about the matter.  🤔

    (The Times is well-known in the UK as the newspaper that the upper class and intelligentsia write letters of complaint, etc, to.  Out of idle curiosity, is there a German/Austrian equivalent newspaper?)

     When it comes to quality press, I would name "Die Presse" and "Der Standard" as Austrian daily newspapers, maybe additionally the "Salzburger Nachrichten".

    In Germany its "Die Zeit", "Süddeutsche Zeitung" and "Frankfurter Allgmeine" and in Switzerland probably the "Neue Zürcher Zeitung".

     

    However, it is quite possible that the tradition of writing letters to the editor is not as strong here as it is in the UK.

     

    The retro-causal button sure would be worth an entry in the ideas section here in the forum 😉

     

    BTW, some forums actually have a popup message when someone starts posting a reply and one forum I frequent actually won't allow starting a post as long as someone else is working on his answer and when you start an answer you have to fill in a form and answer questions like how long approximately you think it will take until you finish answering.  The famous German thoroughness is often not particularly cozy, which can easily put off a trained Austrian 🙂
