Hello everybody,

I'm really new to Smath and i am having an issue with the while loop. How can you write multiple conditions for your while loop. While a>b && b>c && c>d.

Would really appreciate some input.

If you want to piece wise plot conditional ...
if/otherwise ... as any as you want to condition.
From the directed visit Samples, iterative is bidirectional.
Or multiple conditional Golden ratio
More advanced conditional is generally Bolean... Example attached.
Show something of your Creation.

In the boolean toolbar, you will notice "AND" and "OR" operators, denoted as ⋀ & ⋁ (respectively).

On that note, to specify more then (1) command under your while loop; utilize the "line(" command.

As such, you can copy and paste the following:

line(a:20,b:5,c:1,d:0,while(((a>b)&(b>c))&(c>d),line(cc+(b:b+5)),a:a+1,d:b*(-1),3,1)),stack(a,b,c,d),6,1)=#

I hope this is of Good Help;

... Bolean composite style.

There are also;

ltlt(), altle(), alelt(), a≤blele(), a≤b≤c

gtgt(), a>b>c
gtge(), a>b≥c
gegt(), a≥b>c
gege(), a≥b≥c

These functions are part of Custom Functions plugin.
Unfortunately, it supports only three arguments.
Despite that, some boolean expressions may shorten drastically.

Regards

line(a:20,b:5,c:1,d:0,while((gtgt(b,a,c))&(c>d),line(cc+(b:b+5)),a:a+1,d:b*(-1),3,1)),stack(a,b,c,d),6,1)=#

I've never thought about it, but I think that maybe I can add set of functions with unlimited arguments (>1), gt(#) ge(#) lt(#) le(#)

Would unlimited versions be mixed or same boolean expression?

... interesting, however very multiple-specific.

In addition to gt(#) ge(#) lt(#) le(#), some notes about a relseq function.

that way, it would be same boolean

lt(a,b,c,d,e,f)=a<b<c<d<e<f=(a<b)&(b<c)&(c<d)&(d<e)&(e<f)

That's a good concept, I think that probaly it's feasible. I'll give it a try.

this maybe?

also, prefix/postfix functions can be made for unlimited arguments.

I've tried something like postfix(F,x,y) but it isn't really user-friendly (e.g. it can't be used on the LHS of an assignment because it overvrites the postfix() function itself)

Hi Davide. Great implementation. But I'm thinking in ways to write set union a U b, intersection, function composition like f o g (x) := f(g(x)), logical binary operators like implies, iif and similar stuff.

Best regards.
Alvaro.
