Hi all,

I am running xmaple via linux, version 17.

This is on a Unbuntu OS X64 with i7 940X, and 4G RAM.

Hi,

I am using Maple 15 on a school server. In most of the times, the following screen occurs:

Can I get rid of that notice? My results got disappear very quickly to the TOP.

Is that something I can change or it has to be done from the admin?

And just a general question, do Maple run more or less faster on Linux/Unix machine than windows?

Hi all,

For research purposes, I have symbolic matrices of dimentions up to 100 x 50 (and above) with certain number of parameters. Then giving random value to those paramters, I want the numerical rank of the matrices.

Maple 17 does not seem to work well with symbolic ranks, where expentials are involved.

And more to it, both

Student[MultivariateCalculus][Jacobian]

and

VectorCalculus[Jacobian]

does not seem to work. ...

Hi,

> seq(seq(p[j,c],j=2..3),c=1..3)=seq(seq(1/(1+exp(-(mu+cat(tau,j)+cat(eta,c)+mix[j,c]))),j=2..3),c=1..3);

Basically, I want to use these expressions in subs.

How do I tell Maple to make the substitution of "lhs=rhs"?

(in the form of {p[2,1]=something,p[3,1]=something,p[2,2]=something,p[2,2]=something,p[2,3]=something,p[3,3]=something,})

I can then use subs() to replace them in my desired expression.

Hi all,

I just learned about the with(Threads) package and I wanted to do a bit testing and see if it's 'faster' or more 'efficient'.

This was done on a i7 940X (QuardCore) laptop.

I dont really see how it is better in a sense?

Or am I using Seq for the wrong purpose?
