Hi, i got a litlle problem with fromats, i m realy bad at this.
i got procedure 'getone(z::list)' i was execute it like this  
>getone([seq(lineP[i], i = 1 .. pm)]::list)
where lineP is 

>pm := 3;
>rollx := rand(98.0 .. 102.0); rolly := rand(-1.0 .. 5);
>rolll := rand(.5 .. 1.0); rollf := rand(0. .. evalf(2*Pi));
>rollm := rand(0. .. 20.0);

>for i to pm do lineP[i] := [rollx(), rolly(), rolll(), rollf(), rollm()] end do;

it's pm times of z:=[rollx(), rolly(), rolll(), rollf(), rollm()] ::list

and i need make optimization work for any pm=1..100; with rabdomly generated iteration point as above.

The main queston is how make minimize as below
Minimize(z,variables=[z],   initialpoint={z=[seq(lineP[i], i = 1 .. pm)]},iterationlimit=1000,optimalitytolerance=0.01)

work with z::list kind of 

[[100.7798614, 1.109653266, 0.9840371500, 4.257816686, 9.737110573][100.0135459, 0.887539481, 0.9144164697, 3.980093624, 7.343851161][100.0661308, 3.724268229, 0.5020544909, 2.052134822, 14.37408543]]

I find fsolve() to be curiously unstable. Some of the behaviour I can guess at, but other parts are not as clear.

Define a function.

P := x->fsolve(exp(-(1/100)*t^2)*cos(2*t),t=x):

plot(P,4..5,smartview=false);

I'm begginer in maple so I have many questions

I have 

f1 := [x2^3-3*x1+x2, -x2-x3+u, x2-2*x3]

I want to put 

x1=2*x1

x2=2*x2

x3=5*x3

and I wand it in loop

for x4,...xn

so that f1 will be a vector

I set up a worksheet with embedded components in Maple 18. I am now trying to use the worksheet with Maple 2015. The GetProperty( ) procedure in DocumentTools cannot find a number of kinds of the embedded components (perhaps all kinds).

Why would this happen, and how can I fix it?

I have few packages downloaded from following link:

http://cpc.cs.qub.ac.uk/

Following are packages that I need to install on Maple:

Rif: For differential elimination.

GeM: For computing symmetries and conservation laws for nonlinear PDEs.

wkptest: For symbolic computation of Painleve test for nonlinear PDEs.

My problem is to install these packages onto Maple, but I do not know how to do this. For example, the package Rif contains file like maple.hdb, maple.ind, maple.lib, but I do not know what to do with these files. I shall be grateful to auduience of Mapleprime if somebody can help me on this.

I would have love to attach a document because I try pasting it but it is not allowed I want to integrate something of this nature;... I don't even get how to write anything here maybe because am using a phone.53e77f9f0cf21cc29fd9d4e8.pdf 

This is the paper i'm working on,

1) I couldn't get 11a and 11b on page 1918.

2) I don't know how to integrate 13b to 13e. Please somebody help my career I will never forget it.

Hello

I have a simple list:

xlist := [150, 250, 500, 800, 1300, 2500, 5000]:

ylist := [.3, .5, .8, 1.0, 1.2, 1.4, 1.6]:

where after i said x:=plot(xlist,ylist);

What I want to do is ask maple" At what x value does the graph intersect with 1.5 on the y axis" or "at what y value does the graph intersect with 3000 on the x axis". 

The data points are just that, I've been looking for commands to ask these questions but have been without luck. You don't need to give me the answer if you can point me to somewhere where this information is written, that would be very helpful!

Thank you.

hi.please see attached file and explain how i remove error

thanks alot

Where was this graphic of a mountain crater used in Maple?  The top left graphic from here http://www.maplesoft.com/products/maple/features/Visualization.aspx#

I haven't seen it used in any webinars nor have I seen it in the application center.  5 points to anyone who can find it :)

Hi,

I am a Maple über noob.

I am strugeling to figure out how to do simple phase calculations

For example

Phase_angle.mw

It is mainly for 3-phase angle calculation

dear all

(1-pi*x/2)y[b]-1/3=int(t^4/sqrt((t^2-y[b])^2+y[a]^2),t);

x^2*y[c](1-pi*x/2)-1/3=int(t^4/sqrt((t^2-x^2*y[c])^2+y[a]^2),t);

i want to plot y[a],y[b],y[c] vs x.

plz help me.

thank you 

Dear all

i want to plot this equation can someone help me

v=beta^(-1)(f/2)

beta=(t^(0.5);1/5,1/2)

beta is beta function i want to plot v wrt f

thanks

I wish to display the following screen output from a procedure A(), in a textbox of mathcontainer or any other suitable component.

This output to screen listing is generated by print statements in the procedure A().

I have placed the procedure call A() in a textbox and then am using a button component to execute it with the objective of displaying the above output in another component display box; either a textbox or a MathContainer box...  I can see that A() executes, but do not know how to get the result to display in a component box.

Can anyone offer any help?

hi.may  help me for solve this nonlinear equations by numeric solver maple39.d39.pdfocx39.pdf

thanks alot

Hi everybody,

i'm trying to do an elliptic regularization but i don't know how to proceed ?

Is someone know how to achieve to do that  with an example ?

thanks a lot !

PS: i know only how to do a linear regularisation.
