Non-Linear overdetermined equations - which is best method? with less number of iterations

When I use Jacobi it takes 25 iterations.

Any other method which takes less iterations?

## Saveplot function not refresh in for loop call...

I search saveplot and sleep function here

i had kept close filename function and move plot setup default to first line

but thread no sleep in maple 12

then I remove sleep and can save image file

but after I call it in a function and run a for loop for this function

the file is not updated after sleep 3 seconds

how to run a for loop call it and it can refresh

## How to print a specific (large) coefficient of a q...

I'm very new to Maple (and coding in general). I'd like to know a very large coefficient of a certain 𝑞-series involving the Dedekind 𝜂-function. For example

`s:=series(subs(q=q^6, eta^4), q, N);`

where `eta := series(q^(1/24)*product(1 - q^n, n = 1 .. 100), q, N)`. I know the command `coeftayl(s, q=0, N)` but for certain 𝑞-series it doesn't recognize the numerical value of this coefficient when 𝑁 is too large (even after subtracting the principal part of 𝑠, if there is any) - instead it realizes the coefficient as a HUGE limit of something. Cheers.

## How to get all n nodes(n<=15) Non-isomorphic  conn...

I'd like to get all at most 15 vertices Non-isomorphic  connected  bipartite graphs. One way is to use the function NonIsomorphicGraphs(k, output = graphs, outputform = graph, restrictto = connected).

`with(GraphTheory):`

```k:=8; s1:=[NonIsomorphicGraphs(k,restrictto = connected,output=graphs,outputform=graph)]: bipartitegraph:=select[flatten](x->IsBipartite(x)=true, s1): nops(bipartitegraph);```
But when k=9, it is slow, I doubted that the code

By Checking out the encyclopedia，http://oeis.org/A033995 , we knew the following number of bipartite graphs datas of , at most 14, they are not many（the datas contain  no-connected conditions)

awesome.

Ps： I know  in SageMath  we can get all bipartite graphs quikly even though n>=10  by  using the

for g in graphs.nauty_geng('-c -b 10 -g'):

But I hope it can be realized in Maple.

Thanks!

I am thinking of running maple in google cloud. Does Maplesoft available in google cloud

## How to fill in missing data with statistics?...

If I know the direction of up and down

how to control normal distribution to fill in missing data to the direction I want in maple?

just like fill in missing pixel in bitmap file.

Is Maple capable of printing functional html links? That is can a Maple code output an html link that actually works?
