## how to sort a coordinate points...

hi everyone,

I have a list of coordinates  and would like to sort them so that in the new order, the last coordinate will be the first coordinate and the first coordinate will be the first:

for example:

P:=array([[1,4],[2,3],[3,2],[4,1],[6,5],[6,1]]):

should sort to

P:=array[ [6,1], [6,5], [4,1],[3,2],[2,3],[1,4]]

## how to solve 2 implicit functions...

Hi, I cannot solve the 2 implicit functions with 2 unknown (m,n) simultaneously (please see attached maple file). Note: m and n are real numbers.

## combination of for-loop and while-loop.....

Hi,

I wondered if you would be able to help.

I've set up a for-loop and while-loop that substitutes values of j and k into a given function

I want to get the answer for every right for example right[1], right[2]..but this code give the answer for right[1]nd right[6] only..

P := array([[1, 4], [2, 3], [3, 2], [4, 1], [6, 5], [6, 1], [6, 2], [5, 3]]);

j := 1; k := j+2; Fold := 0; Fnew := 1; counter := 0;

## How should I Write Codegen[Fortran] output results...

I have a maple classic code. at the end I convert a parametric matrix to fortran77 code. in optimized mode

now I need to edit the Fortran77 code to Fortran90. for this job I have another code to do that.

but how should I write the codegen output to a test file?

## function with n variables...

Hi,

I have a function of n variables

y := (a,b .. n) → ....

For this function I need also n input values

y(x1,x2, ... ,xn)

The vector x has the input values ("x1,x2, ... ,xn") but how can I call them without typing them one by one?

Any ideas?

## How to compute the integral: int((c-x)/x)^n,x=a..c...

How to compute the integral: int((c-x)/x)^n,x=a..c) ?

This integral is an incomplete beta function and could be expressed in terms of hypergeometric function, but my Maple refuse to deal is. Pleas help

## Why isn't -b+sqrt(b^2)=0?...

I tried the following, but did not get 0. Why not?

>restart;

>b:=3*beta*Pi*(3-4*cos(z)+cos(2*z))/(16*z);

>-b+sqrt(b^2)

I know I can do this by hand, but this is part of a larger equation which I narrowed down to this issue.

## Solving a system of recurrence relations...

Hi,

I'm using Maple 14 and I'm trying to solve a system of recurrence relations with initial conditions (a Vector Autoregressive model). The system is

const:=Vector[column]([0.009421681, -0.0005441856]):
lagY:=Vector[column]([0.796519372, 0.0179147112]):
lagZ:=Vector[column]([0.133049059, 0.5240695764]):
A:=<<const>|<lagY>|<lagZ>>;

eq1:=y(t) = A[1, 1] + A[1, 2]*y(t - 1) + A[1, 3]*z(t - 1);
eq2:=z(t) = A[2, 1] + A[2, 2]*y(t - 1) + A[2, 3]*z(t - 1);

i am very bad at English so you ignore my mistake

i am beginning start use Maple therefore i don't know use Maple.

Like title, i have a circuit CLR with transer function H=

## How do I integrate this function?...

Hi,
How do I complete the integral below? I'm not sure what the resulting function looks like, but it will be a function of n where epsilon is a real constant. My ultimate goal is to graph the resulting function where epsilon is equal to -0.4.

Thank you.
