new lmtx beta

new lmtx beta

[Hans Hagen]

Hi,

I uploaded a new beta (mostly lmtx). Challenged by Mojca we managed to 
get native compilation under mswindows working in visual studio (and 
soon the compile farm will do several windows compilation variants) so 
future installation can have either native binaries or crosscompiles 
(they have comparable performance with the native ones being a bit 
smaller). The current upload still has crosscompiled binaries.

Thanks a lot.
What about musl binaries?

Yes, i need to do that (assuming that you're confident that they work) 
.. thanks for reminding me.

It works nicely.

I think that it is better to use the same name if there is no special reason to distinguish, and I prefer to use “function | functions”.  
However, I am OK whether you keep both or choose one. 

Thank you and your team again.

we can still decide as it's beta ...

   function | functions

or

   code | codelist

(it's basically lua code ...)

i have no preference and as you're the first to bring it up you may 
decide ... (unless others can convince you otherwise)

Dear Hans,

I read the manual of luametafun and do some examples.
Thanks for many new features.
It is  really great.

I’d like to ask two things. 

1. On  page 26,27, in the manual, 
> 
> http://www.pragma-ade.com/general/manuals/luametafun.pdf <http://www.pragma-ade.com/general/manuals/luametafun.pdf>

a function name of the graphics are appeared as same as in the argument ‘function = “x^2 + y^2”’. 
Though it calculates function using “x^2 + y^2”,  it is better to write the name of it as the output of $x^2 + y^2$.
Is it possible to write  it as in mathematical form?

2. To define a mathematical function, it uses “function = “ in Contour, while it uses “code = “ in Surfaces and in Functions.
Is there any reason to use two different names “function” and “code” to define functions?  

Thank you again.

Best regards,

Dalyoung

Hi,

I read the new manual with a great joy! This is really nice improvements of
MetaFun! I also like the 3D plots!

I had the possibility to try out some contour graphics on a freshly updated
system. I have two questions:

1) I think the first (blue) plot looks fine and it looks like it could be
the same curve as the blue one in the Mathematica plot (page 3). Why does
my second example (orange) not match with the result from Mathematica
(orange)? (I think I do something wrong)
2) Is there a way to combine the two contour plots in one MetaFun drawing?
If I add them both to the same, only the last one shows. If I try
functions={"-4+x^2+x^5+15*y-y^2-10*x^3*y^2+5*x*y^4","-15*x+2*x*y+5*x^4*y-10*x^2*y^3+y^5"}
it does not show both either.

new (lmtx) beta

[Hans Hagen]

[-- Attachment #1: Type: text/plain, Size: 548 bytes --]

Hi,

I uploaded a new lmtx beta. Again some more metafun trickery (see 
luametafun manual). I attached an (lmtx only) example of some experiment 
code, dedicated to Alan Braslau (teacher among other things).
