Ok, I've got a matrix where the elements are lists of length 3, the first element tells you what sort of entry it is; the important thing to know here is that if the first entry is one then the second entry (and third) is a variable.

Hi, I'm currently using MAPLE 11

I'm trying to multiply series(about 30) matrix[ Matrix name is(F(x[k],y[k],j[k])) by using the product command

i.e.

product(F(x[k],y[k],j[k]), k=1..10); 

when I use the above command the following. error occurs.

[Error, (in rtable/Product) invalid arguments]

I've figured out the product command only works for real numbers, not matrix

But the problem is ... then what command should I use?

Ok I have already defined f as a procedure earlier on, so here is where i am having a problem:

Hi Guys, im wondering if you can help me with this for loop problem

so i have the array k[20,20], so it has 400 hundred entries, each entry has a number, but one entry has a number higher  then the others,

e.g. k[1,5]=6,k[1,6]=40,k[4,4]=20

so in the loop below i intend for the a and b element of the entry with the highest value to be assigned to tempa[2,1] and tempa[2,2], but i am not getting this outcome, please have a look

My sincere apologies for this incredibly elementary question.  I just can't find the answer.  Please refer me to an appropriate resource for this information if you know of one so that I won't bother the forum with such inane questions in the future.

Here is a simplfied example of what I'm trying to do (when my code didn't work, I created progressively simpler examples until I got to this):

--------------------------

a := array(1..3);

for i from 1 to 3 do

    a[i] := t -> i*t

end do;

Hello,

                 Is it possible to view a table of values of a function? if yes please help. For example in TI calculators a table can be viewed after plotting a graph.

for example

f(x) = x

x         f(x) 

1         1

2          4

Basically what I would like to do, which seems self-explanitory but is obviously not in the right language for maple is this (this is for a local M within a procedure where P is a matrix already defined).

TemplateMatrix:=proc(P) local M;
M:=Matrix(3, if P[i,j]=1 then (i,j)->x[i,j] else (i,j)-> P[i,j]);
M
end proc;

basically what i'm trying to do is turn P which is currently just a matrix of numbers into a matrix which has variables where the number 1 was previously an entry.
 

There are a number of facilities in Maple which may be extended. Included amongst those are `type`, `print`, `evalf`, and `latex`. The help-page ?extension_mechanism claims that all the built-in functions allow for extension. It also mentions a few system Library routines such as `verify` (but does not mention `latex`).

There are some descriptions of varying completeness in a few...

I'm a very new user - apologies if this is answered elsewhere on the forum - I've tried searching but haven't found the answer.

I'm trying to evaluate something which relies on the fact that sin(nPi)=0 for integer n. How do I get Maple to do this? I have tried:

a:=m*Pi   (sorry - haven't worked out how to post actual Maple input yet)

m::integer

y:=sin(a)

But when I evaluate this, it just gives me sin(m*Pi); if I put in a numerical value for m then I do get zero; but I need it to recognise this is the case for any integer.

I am trying to plot the solution of a procedure beta_k(P) vs the input P; however, the solution is a pair of values (k, beta*) and I do not know how to isolate the individual values of the solution.  Thank you for your assistance.

I have a proc and I want to test if the function is odd.

The following is wrong, but could you modify it to work well?

smth:=proc(f::algebraic,x)

if  simplify( f(x)+f(-x) )=0

then print("f is odd");

end if;

end proc;

In the proc argument there is x because x is the variable of f,  for example  f  may have other

parameters,   (in mathematical notation)  f(x)=ax+3.

Thanks,       Sandor

In Maple 11, how do I graph (and solve) a set of 3d inequalities (in x, y, z) to show the feasible set and the vertexes ?

yes, basically i just want to call something "y at x=0", just to make the final presentation of my results better. Is there something similar to # that will stop maple getting confused by the space of the equals sign, and just ignore it as comment/description?

I am trying to find parameters using NonlinearFit and keep encountering the following message:

'Warning, limiting number of iterations reached'

I have not been able to figure out how to overcome this warning - the fits I am getting are
 not very good.

This is mainly an aesthetic thing, but I'm finding an interpolating quartic polynomial given some data points, so I set up a Matrix system of linear equations etc, but I want the output solution vector (i.e. the solutions for the coefficients of x, x, x, etc.) to be to 3sf. I have tried putting evalf[3](LinearSolve(A,b)); but that doesn't seem to work. Even if I change Digits, (which isn't ideal anyway as I only want output to be to 3sf temporarily) the values in the vector solution are still to 10sf.
