Transferring a MC sheet. How can I solve for the unknowns?BJT Circuit Analysis.sm (54 КиБ) скачан 161 раз(а).

For using Linsolve(1) function, you need to put the system of equations into a matrix. The result computes the unknowns in alphabetical order, I believe. You can retrieve this information using Unknowns function.

Many thanks!

You can retrieve this information using Unknowns function.

Unknowns("variable") - ... from f(x) menu
Returns a vector of unassigned variables contained in "1:variable".
If unknowns are not found, returns 0.

Solutions are returned in lexicographic order ... inspect Unknowns(A)

... thanks for this LinSolve application.

Here is another MCD sheet, converted Smath [circuit application].
Iterative solvers are common in Engineering.

Thanks Jean, for the Solve Treasury worksheet. I updated my sheet splitting the ampere and voltage values apart.

I've modified the LinSolve(1) function and created a LinSolve2(2) function that allows user to specify result order vector. I've named it LinSolve2 to avoid confusion with the LinSolve(2) Maxima Plugin function.
Not sure if this is useful for anyone.

Lovely separation of result.
A useful companion attached, more examples in future.

... thanks for this LinSolve application.

Jean, I believe the original LinSolve function is a snippet created by Martin (mkraska). You can find it within the Snippet Manager in SMath.

I think so ... those gyzmas # are Martin style.
Easy to removed all # ... like this

1. start by the LHS in the program definition
2. put the cursor on the right of the #
3. press F8 to see all selected, in the program core as well
4. once selected, press Backspace ... gone
5. next proceed in the core of the program
6. result => nice and clean

Cheers
