Mathcad Toolbox - Contains analogs of functions from Mathcad - Messages

Coming soon...
The ability to explicitly specify the placement of block elements will be added.
It looks strange, maybe I'll add some numbering: #1, #2, #3, ...

Hi. That's the Mathematica default notation for pure function's arguments: https://reference.wolfram.com/language/howto/WorkWithPureFunctions.html
Best regards.

Plugin updated.
Changes:
- fixed image handling functions (READRGB(),...);
- the appearance of brackets has been changed;
- added the ability to explicitly specify an insert for MathcadBlock (##, #1, #2, ...).

Expanding the idea of numbering, we can add syntax:
## - take all as sys|mat|line
#i#j - take from i to j
##j - take from 1 to j
#i# - take from i to end
and
#i#js - sys(#i,..,#j)
#i#jm - mat(#i,..,#j)
#i#jl - line(#i,..,#j)
#i#jfun - fun(#i,..,#j)
or
### - insert as parameters: foo(x,y,###) -> foo(x,y,#1,#2,...)
##3# - insert as parameters: foo(x,y,##3#) -> foo(x,y,#1,#2,#3)
## - take all as sys|mat|line
#i#j - take from i to j
##j - take from 1 to j
#i# - take from i to end
and
#i#js - sys(#i,..,#j)
#i#jm - mat(#i,..,#j)
#i#jl - line(#i,..,#j)
#i#jfun - fun(#i,..,#j)
or
### - insert as parameters: foo(x,y,###) -> foo(x,y,#1,#2,...)
##3# - insert as parameters: foo(x,y,##3#) -> foo(x,y,#1,#2,#3)

I encountered a plot problem with the list version of rkfixed(). Probably this also applies to other ODE-integrators with embedded function assignment.
In the native 2D Plot:
- When plotting a solution function along with a matrix of marker points, then the points won't display
- Yet, when using lspline() directly, both objects plot without problems.
In X-Y Plot:
- When the independent variable has the same name as the solution function (e.g. x(x), then x() is not treated as a function but as the expression x (similar with v(v) or any other name).
- A workaround is to use a variable name different from the function name. Yet this is strange, because in SMath x() and x usually are independent objects.

A little step further? (And I say little because I'm not the one who has to improve the code) Take #arg as function parameter?
Best regards.
Alvaro.

I want to add a set of simple examples to the Mathcad block context menu that demonstrate how it works. Can you suggest such examples?
Similar to the X-Y Plot component. In this case, you will be able to fill in not only the input values, but also the description. You can insert arbitrary expressions inside the component.
Imagine that you can formalize the solution to a simple problem. What would you suggest as educational examples?

I suggest a handbook like Martin's one, with examples where the user can reuse the code (Code reusability is the technical expression for when you don't want to say that you are going to copy and paste). Or like Mathcad quicksheets. This is my idea of a clean use of the block for solving high school problems.

I'd like to have such things like nsol in SMath core.
How about embedded assignment, similar to FindRoot? I don't like poking the values out of S. I see that this might reduce flexibility, e.g. in the case of parametrized initial guess.
I tried to demonstrate a generic approach, i.e. you get the variables assigned without having to issue any specific command except for the generic content of the placeholder. It is just a try and fails with single variables but you get the idea.
Of course, one would like to have a solve block without the cryptic generic expression in the placeholder.
Perhaps, such a block could be created from the insert menu with pre-allocated content of the placeholder and with setting it to hidden.

Hi Martin. I put "0" as argument because there are no more args. The second could be a vector of options, like this:
or the solved variables. Also, I use "S" because this error, which I imagine that could be corrected, but don't know how hard it could be:
Best regards.
Alvaro.
PD: Notice that x# : transpose(str2num(x#))*diag(U#) or x# : diag(U#)*str2num(x#) if you want to return the answer as column vector, like normal people, returns x# as scalar if length(x#) = 1.

Hi Martin. I think the opposite: the implicit assignment of the names of the variables sought to a solution makes its call very rigid, since many times there is no direct relationship between the variables of the equation and the names of the variables that are intended to be assigned to the solution, as is precisely demonstrated in this case
Another variant among many would be to find a limiting speed and call the result v.lim, even though the variable of the equation is "v".
Best regards.
Alvaro.
