Maple 9.5 can not be installed on my Suse 10.1 System. Invoking the command ./installMapleLinuxSU leads to the following errors: Preparing to install...

What is Way to improve matrix calculation speed in Maple session? 1 LinearAlgebra Solve in Maple session 2 Maple Comand Line mode 3 OpenMaple technology without big resourse of interface. 4 Matlab Connection by with(Matlab); 5 What quality of dual chanel calculation Do you know any information about it? BEST THANKS...

Suppose a function is given as f:=[[.4,.2,.7],[a,b,c]]. How this can be done that writing >f(a); would give me .4 Thanks.

I have a user defined type named FST which is like [list of numbers between 0 and 1 inclusive,list of names]. I now want to change union of two objects of type FST to be as maximum of evry pair of corresponding elemnts of first sublists. For example suppose A:=[[.3,.4,.2],[a,b,c]]; B:=[[.7,0,.2],[a,b,c]]; Then writing >A union B; should give [[.7,.4,.2],[a,b,c]] Thanking in anticipation.

To mark the end of eleven very fruitful years in residence at the University of Waterloo, I have written a goodbye essay. The title and abstract appear below, along with a link to the full text. The essay describes my long-term research goals and presents my personal vision for the future of the areas of mathematics in which I work.

I'm working with inverse of a complicated matrix, which is 12*12, and all the elements are symbols. The program is running forever, no results, no error message? Anybody has such kind of experience, any suggestion that what I can do? Thanks a lot, I appreciate your help!

Suppose we have two sets A={a,b,c} and B={a,c}. And we write > A union B; we get {a,b,c}. But I want this to be replied as A only. How this can be done? Thanks.

Hi, all. I want to write viewer/converter for mw/mws, so mw/mws format description needed. Google say nothing about mw/mws format. search.maplesoft.com likewise. Can somebody help me with mw/mws format description? Is it possible to obtain such info from Maple developers? Is reverse engineering of mw/mws prohibited?

I just moved all my MAPLE files to my new laptop. Icons from Maple9.5 files made on a windows machine are missing and files do not open at all--error message -10814. Files from an imac running 9.5 also do not open when double clicked but can be opened after selecting the "Open With Maple 9.5". This has to be done one file at a time. The system has Java 1.4.2 and 1.3.1. Any help appreciated. Thanks, Roger

Playing with the integral int(cosh(v)/sqrt(sech(v)-sech(vm)),v=0..vm); I have tried numerical integration with different methods and got errors for small vm. Eg. with plain N2:=vm->evalf(Int(cosh(v)/sqrt(sech(v)-sech(vm)),v=0..vm)); N2(.01); returns unevaluated, and with the NAG method N3:=vm->evalf(Int(cosh(v)/sqrt(sech(v)-sech(vm)),v=0..vm,method = _d01ajc)); I get these error messages: N3(.01); Error, (in evalf/int) unable to obtain a real result N3(.001); Error, (in evalf/int) NE_QUAD_ROUNDOFF_TOL: Round-off error prevents the requested tolerance from being achieved: epsabs = 5.0e-013, epsrel = 5.0e-010.

Currently (in maple 10.04 and presumably earlier), Maple refuses to expand the natural log of an abstract product, so: v1 := ln( product(x[i], i=1..n) ): expand(v1) assuming positive; yields: ln( product(x[i], i=1..n) ) (Note the use of "assuming positive" so this makes sense mathematically.) The funny thing is that, if you print(`expand/ln`), it looks like they're trying to handle this situation: ... elif type(x, 'product'(anything, anything)) then s := signum(op(1, x)); if s = 1 then sum(ln(op(1, x)), op(2, x))

Hi all, Using maple 10 classic version, I am working with the below function of f(x): restart;fx:=cos(x)+2*sin(x);plot(fx,x=0..2*Pi,y=-3..3); I would like maple to show the x-axis values as radian instead of 0 to 6. How do I do this? If I now differenciate fx and find the value of zero I get the answer of arctan(2) fmx:=diff(fx,x);solve(fmx=0,x); Now I would like to visualise this by plotting a line from x=arctan(2) vertically to function f(x). How do I do this?? The maths is in place, its just getting maple to do what I want it to that creates problems ;-) Thanks in advance for any help.

Maple 9.52 outputs 0 to the expression, specified in the title:

> int(Dirac(x)*Heaviside(x+c), x=a..b);
0

while the answer I expect should be: Heaviside(c) if 0 belongs to [a..b], and 0 if [a..b] does not contain 0. In other words, it should be Heaviside(c)*(Heaviside(b)-Heaviside(a)).

Is my expectation correct? If it is, how to force Maple to provide the correct output?

Thanks in advance,
Anton Travleev.

One of my students was surprised at what happened after this command: > plot([sign(x), 'sign(x)' ],x=-1..1,color=[green,red]); I was too. One would expect to see an overlay of the green and red graphs. You don't. Curious. Jim Herod
