There i see

for advanced users, see the routines `simplify/size/size` and `simplify/size/size/object`.

How to write coorectly in maple 15 those calls? From maple 5 (it was ~10 years ago ) i hardly remmember

that f/x also could be treated as function call f  at x or smth. like that...

I am going to use maple in connection with my project concerning non-linear dynamic and chaos, but i have never used the program before, so I hope you guys can help me with that,

I have a model of non-linear dynamic system as following:

dA/dr = k + m * Y(r) - A(r) * B(r) * B(r) - A(r)

dB/dr=1/q * [A(r) * B(r) * B(r) + A(r) - B(r)]

dY/dr=1/s * [B(r) - Y(r)] 

the values of the parameters are:
k= 10
q= 5 * 10^(-3)
s=2 * 10^(-2)

simplify(expr, power, symbol, size);

- simplification by size proceeds 1st or last?

Ok, when I run the below code which maximize the risk adjuested portfolio returns
(long and short positions) in QP matrix form on empirical data I get very strange
allocations ie we go 100% or 100% short in almost all stocks except for a few
where the allocations are more appropriate like 0.2 etc.


# Maximize Risk Adjuested Return Matrix Form
# Minimize W'.Cov.W−W'.EV
# R=Return Matrix

EV := Vector([seq(ExpectedValue(Column(R, i)), i = 1 .. N)], datatype = float[8]):

if maple cannot factor something, does it mean it cannot be factored for sure?

i have a really really long univariate polynomial with coefficients that are also variables (a[0],a[1] etc), is there any tips on how to factor this monster?

thanks in advance!

well first of all this site was very useful for doing my homework, but there is still something I didnt find on it and im sure other people may find it useful.

I have a system of 5 ode's and 6 initial conditions that ive solved successfully and plotted the graphs i need:  Position VS Time

          Speed VS Time

The only thing I initially know is the final position, which i can read on the first graph and...

I've found no questions about these types of functions. When I try to solve this equation by using the FOC function and then try to isolate one of the variables 'effort' (or optimal effort) the outcome is about 6 lines of algebra. When I use simplify it expands even further. What other options are there to get a 'nice' expression?

to find the maximum number of rectan_gles that can be ortho_gonall_y packed into a lar_ger rectan_gle:

1) can some maple code replicate this?

2) but what i really want is: what arrangement of a given a number of rectangles (of differing widths and lengths...

Professor is working in Maple 13  I have Maple 15 just started using this. 

He types 

DE1:=diff(TS(t),t)=3*k[abs]*IO*f/4/r[O]/c[W]/rho[O]-mu*T[O]/(s+1)/r[O]^2/C[W]/rho[O]*((Ts(t)/T[O]^(s+1)-1);

I can not type the math in this format in Maple 15. Can anyone help me, I keep getting error messages.

Thanks

The Standard GUI has an option (Tools -> Options -> General -> Browser) for configuring an installed web browser.  The GUI uses that for its own purposes (for example, clicking on an error message opens the browser at a related Maplesoft site).  Is it possible for the user to access the configured web browser from within Maple, using Maple code?

I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.

I have been asked to provide more detail about certain critical calculations.

Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.

I am solving ode system in double precesion with digits 16, some results are in power of -16 which are equivalent to zero. How can I ask maple to put any number with the power of -16 or less to be zero?

Thx for the help.

Hello there!

I'm looking for some help with my maple code ^^

Here's the problem:

I have 2 Arrays, A and B. A is an array of points each with its own x and y coordinate ( [[1,3],[5,4],[4,5],...] ) array B is an array of values ( [0.5,0.2,0.1,0.6,.....] ). My goal here is to plot with a dot on each of the coordinates in A with a circle around them of radius of the corresponding value in B. ( the first point [1,3] will be printed on the graph as well as a circle of radius 0.5 ...

I think this is a simple question.  I have a gear train that has an input rad/s and an output rad/s.  I need the output speed graph to read in mm/s.  Basically I just need to multiply the rad/s by 2(Pi) to get rps and then multiply the rps by 2(pi)r to get mm/s.

I'm a university student trying to solve a problem, we've been given a very little maplesim knowledge, mostly gear related.  If someone can help me make a custom probes or plots that would be appreciated.

Hi everyone,

I am importing an .m file from MATLAB to Maple using the command: FromMFile(). The .m file uses a set of huge symbolic matrices with an output of a huge symbolic vector of 36 by 1. Each element of this vecot is supposed to form a second-order differential /or algebraic equation that I am planning to solve using the Maple DAE toolbox.

The problem I have is that while I execute the worksheet, Maple only evaluates the...
