I need to pass these codes that are in Mathcad Prime to Smath, does anyone know how I can do it?

There is currently no converter from .mcdx format to .sm. And there is no one to do it, although it is possible.

Make your MCDX compact/readable not a scratch sheet.
If not too long, make an image, some will inspect.

I don't have the MCDX, I only have the pdf.

In this case, only manually.

But the programming is the same in Smath? I mean, for example the FYN or root function still works?

Not same, but very similar.

Smath has many solvers. FYN from implicit roots(,,,).
roots will solve on the canvas [MACH number]

Not exactly, not case of transit via local definition.
Take care ... Jean.

Yes, they are same.
You just rename y# to y.
And deleted line()'s.
What a cheap act.

# not needed, crowds document

As you offered, Smath looks weird.
End of it.

I have deliberately put to show as it will be calculated.
Variable can be named whatever user wants by the way.
I am sure Lelar is not confused, as he is a new user.
Variable names doesn't crowd/confuse smath users.

Your "silent unit" crap confuses new users, crowds topics.
Your "non related" replies confuses new users, crowds topics.
Your "posting same reply for 4 times" confuses new users, crowds topics.
Your "color racket worksheets" confuses new users, crowds topics.

Hi,

Maybe off topic between overlord and Jean Giraud's conversation, but what's the difference between a function definition with line() and a definition with line() removed? Will there be a difference on how SMath calculates it?

Cheers.

There will be a difference, a huge one actually.
When a variable is defined before function,
and that variable is used inside the function,
if line is used, variable redefine shall effect result.
if not used, variable redefine won't effect the result of function.
Which mostly we don't want not effecting, so using line() is better.

I mostly define function variables with unique naming. (# after variable for example)
So common used variable names won't effect function results.
This is my habit and I think it is a useful one.
This naming doesn't crowd pages or confuses people.
It is minimizing calculation errors caused by author.

f(x#;y#):=x#^2+2*y#

Best regards

Thank you for the very warm welcome, Jean.

Is there a reason why Dy is within in eval()? I tried removing it in the function and the result looks the same.

I think this is a very important point that I need to keep in mind. Using unique names in functions is also a great suggestion. Thank you overlord.

Cheers.

Two typos in your 'chito' document: Manilla, Kota Kinabalu in Sabah.
You are right, no need to Dy:=eval(,) is so fast.
eval(,) applies to parse result as a numeric entity.
It breaks the chain calculation. Per application experimental.
The rule eval(,) is crucifying ... watch the demo attached.
from 65 s down to 0.015 s !!!
Take care ... Jean

In simple words, the kernel is a vector of calculated from what to calculate.
In this example, the last that will be calculated is eval([R G B])
It gains 1 min [3/4].

eval() makes computations faster most of time.
Very minor times, may have no effect or slows the calculation.
It would be wise to choose where and when to use it.

Well thank you, glad if I could help.
There are some other tricks to remember as well.
Here is list of which come to my mind at this instant;
  • symbolic/numeric optimization
    most errors can be parsed with selecting the right one
  • Δ temperatures (Δ°C, Δ°F, Δ°Re)
  • not using units for some solvers {solve(), roots()}
    or using multiplications at right place to trick solver as value is unitless
  • using maple() or maxima() for most symbolic results (better support)
  • smath vectors/matrices starts with 1, mathcad starts with 0
    some new users troubles with converting mathcad functions to smath
  • recursive functions shall give an error after 50 steps
    better not to use it, try to wrtie algorithms conventional way
  • eval() for faster calculations
  • line() for functions (not needed always)
  • to be careful for variable names
  • choosing right plot for the right job
