Hello all,

This will be my LAST (I swear) question about translating a little function from Mathematica to Maple.

rand := RandomReal[{-5, 5}, 20]

ListPlot[rand]

ListListLinePlot[rand]

In[16]:= line = Fit[rand, {1, x}, x]

Out[16]= 0.247498 - 0.0131912 x

In[17]:= parabol = Fit[rand, {1, x, x^2}, x]

Out[17]= -1.82858 + 0.31249 x - 0.0082569 x^2

In[18]:= cos = Fit[rand, {1, x, Cos[x]}, x]

Out[18]= 0.483172 - 0.0302095 x - 0.271457 Cos[x]

Plot[{ListLinePlot[rand], line, parabol, cos}, {x, 0, 20}]

#graph omitted by request of users here.

So, then, my LAST question will be :

How to translate this to Maple ?

Thank you very much.

Hello again,

I think I have not been clear enough in my question.

I reformulate :

Is it possible in Maple to create matrices whose elements are also matrices

and this to any level ?

For the Dimensions of a matrix it's ok for me.

thank you 

JM

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
