Hello all,

I have a nonlinear model y=f(x,y,z,p) that I'd like to solve for various value of p (parameter), where f is a system of equations. This model is constrained by a set of inequalities c(x,y,z,p) <= 0.

I coded the model up in Maple in the following format:

f1 := ...;

f2:=....;

f3:=...;

f4:=...;

c1:= x>=0;

c2:= ....;

etc.

To solve this, I type:

i got a set of roots of nonlinear equation by fslove method.e.g.

y1:=a^4+b-3=0;

y2:=a^3+b^2+2=0;

fsolve({y1, y2})

⇒{a = -1.402752934, b = -.8719054433}

i got roots value of the equation,but i want to continue to use direcly the float values of 'a' and 'b' in my program,but i couldnt ues them by some methods since 'a' and 'b' didnt seem to be assigned.so i had to write the values in a text file,then...

I have a maple worksheet with 2d input:

> for i to 10 do f := proc (x) options operator, arrow; x^2 end proc; f(x) end do;

of course it looks "pretty" in the actual worksheet.

When I export this to Latex I get the standard stuff and this:

\begin{maplegroup}

\begin{mapleinput}

\mapleinline{active}{2d}{for i to 10 do f := proc (x) options operator, arrow; x^2 end proc; f(x) end do; -1}{\[\]}

I ' m trying to plot this parabolas and hyperbollas and all I am getting is like a triangle and a couple of crossed lines. (with or without scaling=constraint)

with(plots):

polarplot(4/(1+1.1*sin(x))):polarplot(2/(1-sin(x)),x);polarplot(2*1.5/(1-1.5*cos(x)),x);

Is it another problem with Maple?

Thanks.

Hi,

i have system of two equastion with two vairable (x,y) and paramater ( b1,...,b4, a,...,a4 ) as follow,

q:=b4*(y^3)+b1*x*(y^2)+b2*(x^2)*(y)+b3*(x^3);

q1:=a*y+a1*x+a2*x*y+a3*(x^2)+a4*(y^2);

solve({q,q1},{x,y}):

maple doesnot give any result except o,o solution

can you help me to solve this problem ?

is there any package that able to find the solution reither than numerical method?

i have a same problem , could you please help to solve this problem?

I used maple help to solve my problem but for this one I could not.

I have equation system with 4 equations and variables are for example x y z w .

The problem is I have xy x^2 x^3 yw in my equations so maple with solve could not solve that.

On the other hand,the equation are parametric and non numeric I mean the answer...

I get a data of string type from .txt file,but i want to use the data from string type to float tpye in my program,In fact ,i had tried in many methods,convert,sscanf,type etc.but, i coundnt solve this problem until now.if u know,please tell me how can i do.

example:

x:="0.01"⇒x=0.01

Assuming I have an expression, 'F', I would like to extract from it a factor, 'a', so the expression is displayed as

a*(F/a)

where F/a is a simplified (or expanded or any other displayed form) expression.

As an example:

F:=1 + Q*x^{2} + P*x^{3}

a:=x^{2} / L^{2}

then this will be displayed

x^{2} / L^{2} * ( L^{2} / x^{2} + Q*L^{2} + P*L^{2}*x)

This doesn't seem to work in Maple 13 and 14. However it works in Maple 12.All I get is a static animation plot.

with(plots):animate(pointplot3d,[[[1,2,3],[4,5,3],[2,2,2]],color=blue,orientation=[45,A]],A=45..315);

What am I doing wrong?

Hi

I started my university project 5 months ago and working with maple from that time.

On the other hand,the equation are parametric and non numeric...

Hi, can someone tell me how to approach converting an expression is z to one in powers of z^-1?

For example, express f(z) = z/(z-1) as 1/(1-z^-1) ?

Thanks

I have a inserted code-edit region in Maple-14.The first line says restart: and then I have some data.When I collapse the code edit region is says restart: beside the icon.I dont understand why Maplesoft has not fixed such a "leak" ?For me such small things are highly important because when you use maple on a daily basis such small inconsistencies will give grow you a cancer.Another thing, why cant I programmaticaly load a matrix with data into a code

I had my traditional right-hand-side dock pannel in Maple 14 whichincludes Greek, Components etc. Then I selected componentsand droped it on the righ-hand side of the screen, which gave me a dock on the right-hand-side of the screen.

Now the problem is when you want to remove such a right-hand side dock.The arrows are extremely small which means that it is extremly difficult tosee them yet alone click on them. Most of the time when you have your mouse on them

I am wondering if the export to pdf function has been improved in maple 14?When I used such a function in Maple 13 the result was extremly ugly ie thepdf did not show up as it looked on the screen ie in Maple. Some tables were split on new rows, some table text did not show up at all, table orphance, text orphance, etc etc. I would actually prefer that such a function "export to pdf" is removed than having such aflawed function included in Maple....

There's a bug when using colorstyle=HUE. Maple isn't displaying the proper number color values.

restart;with(plots):

a:=Matrix(1..4,1..4,rand(1..4)):

listdensityplot(a)

listdensityplot(a,colorstyle=HUE)

The colorstyle=HUE only shows 3 colors (value 1 = value 4) but it seems ok in the greyscale plot (4 different values, 4 different shades). Seems to me like the HUE scale is n-1 number of values short.

Looks like a bug?
