Question about maple/xmaple as terminal programs.

segfault — Wed, 11 Jan 2023 21:59:05 Z

Before answering, Please Note,

Do not suggest I use

maple <filename.maple>

The conversion in maple to convert an ".mw" file in xmaple for a text file to be executed with

maple command

does not work and I therefore need a way to execute and operate a ".mw" workksheet straight in terminal without the need for X.

This is a Linux based question.

I have batches of about 50 maple processes that I run in parallel accross several 32-core and 64-core servers.
I am not using the built in spawning process commands, but rather run a new instance of maple.

Some of these batches need to be developed in xmaple it is just not feasable to do it in a text editor to be executed by "maple"

QUESTION:

Is there any switches in maple that I can run a ".mw" maple file as a terminal operation without starting the interface ?

e.g. how can I run

xmaple <mystery switches> maplefile.mw such that the interface doesnt load but the file is executed completely in terminal without the need for X.

Thanks

Hi,

I would like to instal Maple 9.5 in my laptop, once I already have some few programs for his version. I don't know how much cost Maple 9.5, and how do download it.

I live in Brazil.

Thanks in advance.

Carrijo.

Change PDE into ODE

Sana Gull — Fri, 15 Jan 2016 15:16:28 Z

PLEASE..!! CAN ANYONE HELP ME IN CODING ON MAPPLE 13 TO CHANGE PDE INTO ODE??

MY FUNCTION IS THIS

U[t, t]-U[t, t, x, x]-(aU[]-b*U[]^3)[x, x] = 0

How do I solve this problem?

hi friends

i have a problem in maple with an error

Read'dsnumsort.map';
dsnumsort(Ns(0),[x,y,z]);
for i from 0 to 1000 do;
T:=i/25;
NsT:=Ns(T):
X[i]:=rhs(NsT[C1]); Vx[i]:=rhs(NsT[V1]);
Y[i]:=rhs(NsT[C2]); Vy[i]:=rhs(NsT[V2]);
Z[i]:=rhs(NsT[C3]); Vz[i]:=rhs(NsT[V3]);
KepVec[i]:=convert(crossprod([X[i],Y[i], Z[i]],[Vx[i],Vy[i], Vz[i]]),list);
KepAbs[i]:=norm(KepVec[i],2);
od:

pacecurve({[seq(X[i],Y[i],Z[i],i=0..1000)],[[-1/(2),0,0],[1/(2),0,0]]},labels=['x','y','z']);

but i see:

Error, invalid input: seq expects 2 arguments, but received 4

can you helpe me?

Thanks

maple datatype error

bfathi — Wed, 18 Mar 2015 18:04:05 Z

hi friends

i have a problem in maple with an error

> Us:=subs(G=1,m=1,L=1,U):
> D2r:=[diff(x(t),t,t),diff(y(t),t,t),diff(z(t),t,t)]:
> g:=subs(x=x(t),y=y(t),z=z(t),grad(Us,[x,y,z])):
> IniC:=x(0)=1,D(x)(0)=0,y(0)=0,D(y)(0)=1,z(0)=3/4,D(z)(0)=0:
> Ns:=dsolve({seq(D2r[i]=g[i],i=1..3),IniC},{x(t),y(t),z(t)},numeric);

after this i see :

Error, (in f) unable to store 'grad(U, [1., 0., .750000000000000000])[1]' when datatype=float[8]

meaning it can only store 8 byte hardware floats.
Is this statement true? And how can i solve this problem? Or could/should i use a different data type?

Thanks for your time

Best regards

Maple Euler's method help

Kim Seong Gwan — Sun, 08 Mar 2015 16:17:15 Z

This is the simplest method to explain numerically solving an ODE, more precisely, an IVP.

Using the method, to get a fell for numerics as well as for the nature of IVPs, solve the IVP numerically with a PC, 10steps.

Graph the computed values and the solution curve on the same coordinate axes.

y'=(y-x)^2, y(0)=0 , h=0.1

Sol. y=x-tanh(x)

I don't know well maple.

I study Advanced Engineering Math and using maple, but i am stopped in this test.

I want to know how solve this problem.

please teach me~

IT IS EULER's method
