## QR Decomposition...

Hi, The following worksheet shows you how to use Maple to obtain the QR Decomposition of a matrix. The worksheet demonstrates how to use the Context Menu to obtain the decomposition as well as a stepwise solution for finding the decomposition using the Gram-Schmidt process. The worksheet also contains an example of how QR Decomposition can be applied to find the least-squares solution of an overdetermined system of equations. Watch the

## Regarding powerseries package...

Hello,

I am teaching students "operator analysis" and trying to work with maple. But here I encounter some problems, maybe someone could help me.

I have an operator which returns  powerseries. An operator is implemented in procedure geom (in parameters: s is powerseries and this procedur returns A(s), where A is an operator and s powwerseries):

## Maple For MD simulations??...

I need to program a Molecular Dynamics simulator for classical Mechanics and especially for granular matter..

Maple or MapleSim is most appropiate??Or i should do it with a pure programing language (i.e C++)?

Thanx!

## do loops and sequences...

Hi, I've been stuck on these 4 questions for the longest time. I have an assignment due next week, and I have absolutely no idea what to do! Please help me! (I'm using Maple 12 by the way)

1. Write a do loop to store the sequence [1,5,10,15,20] in a 1-dimensional array.

## multilinear...

Hi,

I have a problem with define(f,multilinear). I want that Maple threats alpha[i,j] as a constant such that f(e[1], alpha[2, 4]*e[4])=alpha[2,4] f(e[1],e[4]). I've added all the alpha[i,j] to the constants, but still, he fails to compute f(e[1], alpha[2, 4]*e[4]).

It works when I add alpha(i,j) to the constants, but then the rest of my program doesn't work, so it really should be with [,] and not with (,).

Thanks!

## 2d contourplot from pointplot3d...

I have a matrix with 3 columns of datapoints (as seen in attached file).

I use pointplot3d to create the below picture but how can I get a 2d contourplot of the data ?

## Fourier Coefficients...

Hello,

if my Fourier coefficient b_n := 4/(n*pi) which is only true for n odd, how do I program this in Maple?

For[n=0,n<1000,n++,

If[Mod[2, n],

c = b_n Sin[n w_0 x]

]

That was my attempt, it's wrong of course. What do I need to add/change?

Thanks!

## basic input with x and xdot where (xdot is deriva...

How does one enter (and evaluate the following expression) in Maple

d/dt [ del(L)/del(xdot) ] = del(L) /del(x)

where "del" stands for the partial differential sign and "xdot" is the
simple derivative of x wrt t?

For example, I have L = 0.5*m*xdot^2 - mgx

Note that I understand f:=(x,xdot) -> 0.5.m.xdot^2 - m.g.x, but can't seem to make Maple realize that xdot = d/dt(x) within the partial derivative del(L)/del(xdot)

## Geometric Applications of Determinants

Maple
Hi! The following worksheet illustrates how you can use determinants in a variety of geometric applications. The worksheet outlines how you can determine the area of a triangle or a parallelogram, and the volume of a tetrahedron or parallelepiped using a determinant containing the coordinates of vertices. The worksheet also shows you how to obtain the equation of a plane through three points, and to determine if three points are collinear, or four poin

## Why not with Maple 12??...

Recently i encouter a problem in Maple 12 that i had not with Maple 10...

More specific:

>g(x):=exp(1/x)+x^3;

>minimize(g(x),x=0.5..2);

with Maple 12 i get:

minimize(exp(1/x)+x^3,x = .5 .. 2)

while in Maple 10 i got the answer..

The g(x) has clearly a minimum in that range of x..

I was forced to take the first derivative and find the roots...

Please can anyone explain me why this happen??

thanks
