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.

Dear all,

In the attached file there seems to be a little calculation bug.

Simply let the file run through. In the fourth line from the bottom CSBt equals a number greater than zero. I copied the same expression in the file's very last line. There the result of CSBt is zero.

The identical expression gives two different results. The "correct" result is zero.

It seems to me that the file is somehow damaged. Has this happened to anyone before and what can you do about it?

Many thanks for your help!!

I would like to print on the screen

where is a variable which obtains its value from calculation, and is a string only.

I tried 

T:=2;

Error, unexpected relational operator

Is it possible to solve this problem?
