How to programmatically paste snapshot of a Manipulate?
If I have AppearanceElements->"SnapshotButton" in a Manipulate[], and then click that button, it generates a nice snapshot of the code for the default parameters. Is there a way to get that output programmatically, for an arbitrary Manipulate[] as an input?
Animating a racecar go around the track
I am have a lot of difficult with the problem. I have a picture of a race car superimposed on a picture of a cicular racetrack, the point of this is the use the animate command to make the racecar go around the track. I've been experimenting all day with how to go about this using map, table, and...
Help needed with code optimization in Manipulate
I'm trying to build an interactive dynamic presentation with Manipulate about the electric field lines generated by an electric dipole (couple of charges). In my plan the user should be able to move the two charges generating the field (through a locator) and there would be a third locator...
Dancing with friends and enemies: boids' swarm intelligence
The latest way I have found to use my expensive math software for frivolous entertainment is this. Here's is a way to describe it. [list] [*]1000 dancers assume random positions on the dance-floor. [*]Each randomly chooses one "friend" and one "enemy". [*]At each step every dancer [list]...
Why does this Manipulate command fail to stop/converge?
I'm writing a program in Mathematica that will demonstrate the bisection method for finding the root of a function. The Manipulate command below does not stop updating for some reason and the value displayed goes to 0. Why is this happening? [mcode]In[1]:= g[x_] := x^3 - 9 x + 3 In[2]:= a =...
Can you find an invisible cow with Wolfram Language?
First things first - don't forget to have your sound on for this game. From time to time the Wolfram Language cow wanders the pages of Internet. Just very recently it visited our Community pages too – [url=http://community.wolfram.com/groups/-/m/t/138400]scroll down this discussion[/url]....
What's wrong in my use of Manipulate
This code contains control system functions, but I'm posting it under Dynamics because I suspect that's where my problem lies. The code below defines a simple plant, and then a generic PID controller. I extract the poles of the closed loop transfer function and try to plot them while using...
Manipulate and ParametricPlot3D incomplete syntax error
I've tried to make a torus such that I can vary the parameters, the code I've typed was: [mcode]Manipulate[ ParametricPlot3D[{(2 + Cos[s]) Cos[t], (2 + Cos[s]) Sin[t], Sin[s]}, {t, 0, tRange}, {s, 0, sRange}, PlotRange -> {{-3, 3}, {-3, 3}, {-1, 1}}], {tRange, 0.1,...
How to export an animation for a numerically solved system
I've been trying to put together a double pendulum animation for my physics project.[mcode]forces = {m1* x1''[t] == (\[Lambda]1[t]/l1) x1[t] - (\[Lambda]2[t]/ l2) (x2[t] - x1[t]), m1* y1''[t] == (\[Lambda]1[t]/l1) y1[t] - (\[Lambda]2[t]/ l2) (y2[t] - y1[t]) - m1* g, m2*...
Using Animate Without Showing Variable Slider
I'd like the animate command to simply animate graphics, without attaching a slider at the top of the graphic Is there any way to do this, perhaps with another command...?
Manipulate graphics not fully loading when playing variable or autorun
My problem is that my manipulate does not 'wait' for the graphics to be fully rendered before moving on to the next step when playing the variable n. See code and picture below: [mcode]unitcircle = ParametricPlot[{Re[Exp[I*t]], Im[Exp[I*t]]}, {t, 0, 2*\[Pi]}, PlotStyle -> {Red}];...
How do you put a dynamic in the limit of ParametricPlot without plln error?
I can run the following code without issue: [mcode]DynamicModule[{\[Alpha] = {1, 0}}, {Show[ Graphics[{{Dashed, Circle[], PointSize[0.1]}, Locator[Dynamic[\[Alpha], (\[Alpha] = Normalize[#]) &]]}, ImageSize -> Medium, PlotRange -> 1.2], ParametricPlot[{r*Cos[t], r*Sin[t]}, {r, 0, ...
An application to automate common data manipulation and analysis tasks
As a long time Mathematica user, in many cases I found myself recreating the same code for the same type of data manipulation or analysis needs. Long story short, I decided to create an application which helps me make better use of my time by automating via a user interface some of those tasks I...
How to create a drawing pad in Mathematica?
I would like to create a Mathematica program that allows one to make a line drawing using a mouse. I know Mathematca provides Graphis Tools for just this puprose, but I neeed to know how to do just the basic drawing using Mathematica commands. The best that I can come up with on my own...
How to export a graph produced by Manipulate - with CURRENT parameters
Suppose I have a graph produced by Manipulate, for exampleManipulate[Plot[Sin[k x], {x, 0, 6}], {k, 1, 10}]and would like to produce a pdf file of the graph AFTER moving the k parameter slider. That is, I'd like to have a snapshot of what is actually being shown on the screen with the...
Plot solutions to NDSolve while solution is being computed
Hello, I am currently using NDSolve to explore the solution to some PDEs, and my workflow is evry straight foward: pose the equations+B.Cs, the choose a method, and have NDSolve do the required computations, and then use Manipulate to visualize the solution as I change one of the variables,...
dynamically draw arrows
Hello, I am new to Mathematica. I trying do a interactive application. I need to move some points with mouse, update them positions and draw them and update the position of another points that depend by them. I have problem with my function drawSystemReference that should draw some arrows at the...
How to dynamically update some variables and some not, wrt RandomInteger?
Hi, What is the correct method to implement the following? Requirement: - We have an array a of randomly generated integers (RandomInteger[]) of variable length n. - We compute and display the multiple t*a for a variable t. - We expect the following behaviour:[list=1] [*]If we change the...
Colour coding with time series sensor data
I have a time series of temperature sensor data of a room collected in xls file. I have made a 3D rectangle to mimic the room. Now I want to change the colour according to the time series temperature data. I am able to import the xls data. But I am not knowing how to change the colour of the room...
How to solve...
Hey, I'm sitting on a Mathamatica program where I have to screen a vector on a plane. So now my problem is, that I have to put a Manipulate command in it where I can change the coordinates of the vector and the plane. I think the solution must be really easy, but I can't figure it out, That's my...
