MaplePrimes Questions

Is it somehow possible to apply the Explore command to a procedure with numerical parameters?
It would be convenient in some cases. For example, let us consider  the following  procedure:
K := proc (alpha, theta1, theta2, sigma, n::posint)
uses Statistics;
t[alpha] := fsolve(CDF(RandomVariable(NormalDistribution(0, 1)), -t) = alpha, t);
 beta := evalf(CDF(RandomVariable(NormalDistribution(0, 1)),
t[alpha]-sqrt(n)*abs(theta2-theta1)/sigma));

As far as I know, exporting an Array or Matrix of plot is not directly possible in Maple 15. Is that right? Is there a workaround?

However, I read a suggestion by dskoog that seemed to work:

I need to plot two sets of data versus the same X- axis. For instanse, I want to plot <1,2,3,5,6> and <23,51,54,65,24> versus X-axis of <1,2,3,4,5>. Does anyone know how I can do this? Thanks for your kind help.

Code must not work in such way. See attach. solve_test.mw

What is the advantage of Maple over Mathematica?

Thank you for your comments.

How opening maple twice and execut 2 programs at the same time. If possible.

Thanks

How to make Maple recognize that: sin(x) +sin(x+Pi/3) is equivalent to sqrt(3)sin(x+Pi/6), and various variants of this expression involving sine, cosine, constants equal to Pi/3, Pi/6, etc? I can do it using the subs finction, but this involves finding the equivalent by hand for each variant. Thanks.

 

Maple sometimes decides that the plot needs to be plotted from -infinity to infinite when I do not want it to.  How Maple decides to do this seems inconsistent.  Some plots having a maximum value on the order of 10^3, get plotted on the infinite scale, while others do not.  On the other hand, other plots having a maximum value on the order of 10^-32 get plotted on the infinite scale, while others do not.  In any case, I would very much like to know what...

I am trying to evaluate integral (-1/rho)*del (p)/del (x) dy within the limits y=0 to y=delta (x). For that I first evaluated (-1/rho)*del (p)/del (x) and stored it in res2. Then I tried to integrate it w.r.t dy within limits 0 to delta (x). I wrote the following Maple lines for the purpose:

Te := proc (x, y) options operator, arrow; T[inf]+(T[w]-T[inf])*(1-y/delta[t](x))^2/(1+2*A*H/delta[t](x)) end proc

PDE := diff(P(x, y), y)-rho*g*beta*(Te(x, y)-T[inf]) = 0

I'm thinking about getting a new laptop (since the current one is kind of outdated). I use a lot of Matlab, Maple and Mathematica and will be doing come cfd computations. I found two laptops which, for the same price, only differ in processor and screen size. One features a i7-2620M and has a 13' screen and the other a i7-2670QM with a 15' screen. What I need to know is if the difference between processors is significant enough for me to turn a blind eye on portability ...

I was trying to solve a PDE with boundary conditions and maple 15 didn´t give no answer. 

Is there something wrong? I'm just trying to solve a textbook problem om electrodynamics in maple.

Ok, I want to solve the below code as fast and efficient as possible.
Since it is an LP problem LPSolve(Matrix Form) should be the best.

The problem is that the default objective function in LPSolve(Matrix Form)
is c'x which creates a bit of a problem since my objective function is not a
function of x. My objective function is simply ur + dr. How can I solve that?!

hello, I am trying to call a matlab function from maple and get error msg.

I did instruction about set up matlab but it doesn't work.

I would highly appreciate if someone could help me out with this. Thanks Sina

Hello everyone. I am new to Maple. I am trying to simplify an expression in Maple. The expression is like:

u := a+b*x+a/x+b*x^7+c

If I use simplify(u) Maple returns the result as:

 (a*x+b*x^2+a+b*x^8+c*x)/x

If I want the result in the form:

u = a*(x+1)/x+b*x*(1+x^6)+c

or

u = a*(1+1/x)+b*x*(1+x^6)+c

 

How should I proceed? Is it possible to do this?

 

 

 

Hi:

I am looking at some experimental data, and am having a funky problem when trying to shift the data. The dummy example below illustrates it. Am I missing something obvious, or can anyone reproduce it?!.. I am usign maple 15 on linux 64-bit.

thanks.
