Dynamic Systems Question
|
| |
I am using Maple 15.
I have an electronic module containing a VCTCXO and a microprocessor to phase lock the VCTCXO to a gps 1pps signal.
It works OK. Some times the system loses phase lock and it takes a long time to stabilize, again.
I am looking at Dynamic Systems to develop a model to play with the... more »

strange behavior in a while loop
|
| |
Hi,
I have the following code for a fixed point iteration in two dimensions:
Restart; with(linalg);
Gt:=matrix(2,1,[2-2*x2,1/2*sqr t((2-x1)*(2+x1))]);
...G:=array@op@unapply([op](ev al(Gt)),x1,x2):
...X0:=matrix(2,1,[0.5,0.5]);e psilon:=1e-12;Nor:=2;i:=1;
...while Nor > epsilon do
X1:=G(X0[1,1],X0[2,1]);... more »

implicit plot : line in 3D
|
| |
Hi,
is there a command in Maple that is able to plot a line in 3D which is defined by two nonlinear equations in three unknowns? ie plot the points (x,y,z) solution
of f1(x,y,z)=0 and f2(x,y,z)=0. Implicitplot3d is for surfaces only if I am correct.
Thanks

Prefix and Suffix Notation in Maple?
|
| |
Hello friends,
I'm a regular Mathematica user, but I find that Maple does some things more intuitively and use it occasionally. However, it gets tedious typing function(arg) all the time. Mathematica solves this by using the prefix notation function@arg and suffix notation arg//function. Does Maple have comparable shortcuts?... more »

Using Units
|
| |
I am stumbling through using units in Maple 15.
I want to express a quantity as 30fT == 30femtotesla == 30*10^(-15)T
I can do 30*10^(-15)T and manipulate it.
How do I use prefixes like femto- (f)?

Series Summation Question
|
| |
I am a little curious about whether Maple can evaluate a certain
infinite sum that fails with Mathematica (I do not have Maple so
cannot test it myself).
Here is the sum in Mathematica:
Sum[q^(-6 + 4*n)/(1 - q^(-5 + 4*n)), {n, 0, Infinity}] /. {q -> 0.1}
This leads to and error,
but
(Sum[q^(-6 + 4*n)/(1 - q^(-5 + 4*n)), {n, 0, 1}] /. {q -> 0.1)... more »

Solve Polynomial
|
| |
Maple 15 does not produce a solution to diff(eq,x)=0; But, one exists.
eqn := (2*x^2-5*x+2)/(5*x^2-7*x-6);
deq:=diff(eqn,x);
solve(deq=0,x);
...eq2 := op(1, deq) = op(2, deq);
solve(eq2,x,AllSolutions);
returns two solutions as I expect.
numer(eqn) is zero at x=2 and x=1/2
denom(eqn) is zero at x=2 and x=-3/5... more »
