Hello all,

I just need a hint how to enter "matrices" in Maple which are lists of lists and so on.

Since I gave up on "math"ematica I would like to be able to enter what is just

below (with the dimension).

Is it doable in Maple...I guess yes :)

M = {{a, {1, a, -0.5}}
, {{b, {1}}}, c + d}
Out[5]= {a, {1, a, -0.5}, {{b, {1}}}, c + d}
In[8]:= MatrixForm[M]
Out[8]//MatrixForm=
a
{1, a, -0.5}
{{b, {1}}}
c + d
In[9]:= Dimensions[M]
Out[9]= {4}

PS: Is a moderator ready to make me with a reputation of 100 in order I can enter tags.

Thank you for everything.

Regards,

JM

Helllo folkx :)

What is wrong in my functions f and g ?

I don't catch the point.

Thanks.

Hello,

The title is misleading.

I can't remember how to enter a vector ( I mean the symbol 'arrow' ) for a vector , say u.

I have a normal French/France kb , so please no Klingon reply :)

So CTRL+SHIFT+ALT+F6 is no answer.

Thank you,

Jean-Michel

Hello Ladies and Genlemen,

What is the command to display a list of *all* the packages in Maple ?

How do you insert an output for exemple (2.1.1) in a worksheet?

CTRL+K is inactive for me...it just adds a CRLF.

Thank you very much and kind regards,

Jean-Michel

Ladies and Gentlemen,

first question :

what is the equivalent command in Maple to display Mathematica :

$MaxMachineNumber/$MinMachineNumber and $MaxNumber/$MinNumber ?

second question :

How do you "call" the result of a command using ((5)) for example.

I don't know if my English is so bad as to understand the question

A solution would be a great relief for me.

Thank you very much and kind regards,

Jean-Michel
