I have an equation that is a function of two variables i.e Cp(beta,lambda). I have to plot several Cp curves on the same graph for a range of lambda=0..15 (x-axis). The 1st curve I want Cp@beta=0, 2nd curve Cp@beta=5, 3rdcurve Cp@beta=10 .... and so on

How can I do this without having to define a separate Cp equation for each beta value?

 

Hello

I have Problem with the Maple command plotsetup, it does not seem to work within an if-statement.

What i would like to do is this:

1. Make a matrix with 0 or 1 as enteries

2. convert this matrix into a list where the 1's are points. (So the Matrix entery Matrix[1][1]:=1 would give the listvector:=[1,1]

3. plot these vectors as graphs and store them with the help of plotsetup

4. changing the matrix and rinse and repet 2,3,4 until satisfied

Hello! I am trying to graph the following: 

dx/dt = -10*x + 10*y 
dy/dt = r*x - y - x*z 
dz/dt = -(8/3)*z + x*y 

where x, y, and z are all functions of time (t). Solve the equations subject to the constraint that r = 25 and the initial conditions that at t = 0, x = -1, y = -1, and z = 1. 


This is my code:
DE*plot3d({d*x(t)/dt = -10*x(t...

I have a data set that represents some parameters at different locations in a (linear) system. The way the data are organized is as 1-d vectors which in turn are combined into an Array. I.e. Array[1] is the first vector; Array[2] the second and so on. Each vector represents a data subset, all subsets are against a common independent variable, call it Knob. I plot one of these subsets like this:

plot(knob,vector[1],style=point);

That works fine & I can replace...

c:=12+10x^4+7x^3-89x^2+65x+4sinx

how do i plot a graph of c,

calculate the roots and check the correctness of all found roots.

Thanks for your kind solutions in advance.

I am fairly new to Maple and trying to understand the dsolve command for numerical solutions and plotting graphs of radial distances and trajectory plots.
This is my code below. All of it successfully brings up a solution apart from the very last command and I don't understand why it is not working. 
I believe the last plot is plotting a trajectory plot but I am not sure. I am meant to use the solution to plot the trajectory plot (X(t),Y9t))=(r(t...

HI,

 

I measured some points. This points are plotted in a graph. Now I want to make a fit on this points.

I now that the fit-function has to be like this:

F = A + B1 x e^(-t/C1) + B2 x e^(-t/C2)

Problem: how can I create a fitting function like that?

 

The best thing I found is the "spline"-fit, but it doesn't work properly. It has to be one lonely function, not a summary of several functions (like spline).

Hi,

 

Im not sure if anyone can help but whenever I plot a graph maple freezes. It looks like the program just refuses to plot it and repeats the command until i get to past where the graph should be at which time it goes back to working fine.

 

Another way of describing the error is, whenever i...

I inputted the folllowing into Maple.

with(plots):
contourplot(x^2*y/(x^4+y^2),x=-1/2..1/2,numpoints=60^2,color=blue);
However it is giving me this error:
Error, (in plot/iplot2d/expression) bad range arguments x = -1/2 .. 1/2, numpoints = 3600
 
I don't understnad why.
My lecturer has completed this graph and I literally just copied what she had written on our worksheet in order to acheive the same...

A very useful feature of the plotting program gnuplot is that you can generate an output which is a file instead of a graph. For instance the following short script

################
f(x)=sin(x)+cos(pi*x)
set samples 5000         
set table "outfile.dat"
plot [0:10][] f(x)
################

produces a  file containing a sampling of the function f(x) on the interval [0,10] based on a grid...

Dear Mapleprimes,

 

I need to plot a graph for different values of a specific parameter, sigma. It would be great if I could plot them in two separate coordinate systems right next to each other, such that I can copy paste them into my article. Could anyone help me with that?

 

Cheers,

Dear Mapleprimes,

 

I have a problem with a graph. I need to plot the following:

 

plot({1/(1-x)}, x=0..2, y=0..4);

 

But I don't want the vertical line at x=1. How do I get rid of it?

 

Cheers,

There is a cool option of dropping one graph from multigraph (after that it goes as separated one). How to get  this dropped structure itself? I.e. i have "graph" component with command AllPlots that itself is

AllPlots:=plots[display](AllPlotsStructure,...);

AllPlotsStructure is a list of plot/textplot.

After all i removed one structure by drag-and-drop on component. How to update AllPlotsStructure correctly?

Need to do in maple smth like that:

i am plotting multiple plots in one graph using the following commands. This has been successful for a different function but it doesnt work at all for the typed function. can you pinpoint my mistake? maple sheet is attached as well.
