I think I have come across with what it looks like a very basic bug using the member function. I get the error message: "Error, cannot determine if this expression is true or false: (3) < 100"  after the execution of the last line to the next code:

>Test:=Array(1..3,[1,2,3]);
>member(3,Test,'l');
>if l<100 then print("yes"); end if;

am I doing something wrong ?? I even checked the type of the variable 'l' and it is indeed an integer...

Hi! I'm running Maple 15.01 64Bit on my Xubuntu 12.04.

I also got Maple 15 installed on my Windows7 64Bit computer to verify the results.

So let's see what is going wrong:

What does work?

int(x^n, x);

Gives me on both machines the correct result:

The basic plot routine in Maple 16 has a serious problem with the domain.  The following is an example.

The domain is correct in Maple 15.  This failure occurs in both Windows 7 and Linux.

I have been generating graphics in Maple 16 using the plotsetup(ps,...) command under Windows 7 and Linux.  Maple tech support has a fix for Linux and has confirmed that there is a bug in the Windows version.  These are a Windows eps (converted to png for uploading) and png of the same figure.  The eps conversion should not do this.

The Export function in ExcelTools completely overwrites Excel 2010 ".xlsx" files with no errors or messages.  The same command works properly for Excel 2003 ".xls" files.  It looks like a bug to me.

Hi
I run Maple 15 on an Acer laptop with Windows 7 and have the following problem:

When my Maple documents become "too" long, some of the vectors I have created seem to become tables instead (without me doing anything) rendering vector multiplications and additions/subtractions impossible (they'll throw an error; something like it not being possible to multiply a vector and a table. As if one of the vectors in my multiplication has become a table). Should it...

A common example to emphasize that it is not OK to bring absolute values inside the integral compares

abs( int( cos(n*x), x=0..Pi ) ) asuming n::integer

and

int( abs( cos(n*x) ), x=0..Pi ) assuming n::integer

Maple correctly formulates the first to 0. But the second expression gives it more trouble, returning two messages:

Warning, unable to determine if (1/2)*Pi*(1+2*_Z7)/n is between 0 and Pi; try to use assumptions or use the AllSolutions option
Warning, unable to determine if (1/2)*Pi*(1+2*_Z8)/n is between 0 and Pi; try to use assumptions or use the AllSolutions option

I think I have found a subtle bug in my Maple 9.

If I execute the following code:

###
 B:=[ 3.5, 0.0001, 73.45]; A:=[[seq(1/op(j,B), j=1..3)]];
 writedata("a.txt",A);
###

the output file a.txt contains the line
0.2857142857    1       0.01361470388
(beware: maple has written "1" instead than "10000"!)

Questions:
1) is this bug already known? Is there a patch?
2) does it affect newer versions of Maple?

I have come across this previously but I never had the energy to report it.
The problem is that there exist a bug in Vector[row] when n>10.

For example run the below code:

restart:
with(LinearAlgebra):
a1 := Vector[row]([seq(w[i], i = 1 .. 5)]);
a2 := Vector[column]([seq(w[i], i = 1 .. 5)]);

a3 := Vector[row]([seq(w[i], i = 1 .. 20)]);
a4 := Vector[column]([seq(w[i], i = 1 .. 20)]);

a1.a2;
a3.a4;

   ...

Dear,

======================== This code will give error ============

restart;

with(Statistics);

i:=1:

RandomVariable(ProbabilityTable([1/2,1/2]));

=========================

I  used Maple12 and had a hard time debugging my code to find the error . Finally, I found that when we assign the name i a value, then the RandomVariable(ProbabilityTable([...]) will give error message below:

Error, (in Statistics:-Distribution...

with(Statistics):
Phiinverse := (x) -> Quantile(Normal(0, 1), x) :

evalf(Phiinverse(1-1/2^24));

and the result is 5.691523310-2.147372008*I

Now, I can get a real-valued solution to this by using the equivalent
functionality from stats instead of Statistics.

with(stats):
PhiinvClassic:= (x) -> statevalf[icdf, normald[0, 1]](x):

evalf(PhiinvClassic(1-1/2^24));

1) Compile under vc express 2010 debug config. Don't forget point out your location of maplec.lib in configuration properties/Linker/General/Additional library directories. Assure that configuration is at least Debug or all.

2) Run sheet test_bombard.mw from Debug directory.

In regards to executing a command to output text in color I have stumbled across a minor bug?

I'm having the problem reported here back in 2008 and more recently in 2010:

http://www.mapleprimes.com/questions/96487-Graphics-Output#comment96501

I'm not sure when the axiswidth, axisheight options of plotsetup got broken for me. I'm not certain, but it looks like I was able to control the width and height of my plots not so long ago (version 14 or 13) or am I mistaken and this bug,...

When I type

cos(x), sin(x)

and start the Plot Builder (using the contextual menu) the first option it gives me is for a 2-D plot.  However, when I type

cos(x), x

and start the Plot Builder the first option is a 2-D polar plot and the "standard" 2-D plot is nowhere on the list.  Is this a known bug?  (I'm using Maple 15.01 on Windows 7.)

Thanks,
