CONTOURPLOT MATHEMATICA DOWNLOAD

Perhaps your formatting choices happened to make it more difficult to spot in the ContourPlot. There is no literal Tooltip appearing in the held expression passed as an option, and as a result Mathematica doesn't plot any contour tooltips with this approach, despite the fact that Function would normally be an admissible replacement for the & construct that was used above.As mentioned in comments, it's a PlotRange issue that can be solved by adding PlotRange -> All. points CasesNormalplot, Linepts, :> pts, Infinity (I assumed here that each Line primitive contains exactly one line, as it is true for the current ContourPlot implementation. Its not the sign change but your one extreme negative value the the automatic setting has decided to exclude from the plot range. To see that ContourPlot parses its ContourLabel option in this non-standard way, one can try this: Clear ĬontourPlot, For getting points of individual lines one can use Normal.

In other words, the first argument of Tooltip in the ContourLabel option could equally be replaced by # or Null or blah, because the held form of Tooltip that is given in the option is parsed in such a way that its first argument is always taken as the slot into which the contour line is later inserted, no matter what you put in at the time when you specify it as an option. Contour plot mathematica mesh aramsamsam download mp3 Veeb6. But all other slots such as #1 or #3 are unused. This seems to be happening in the ContourLabels option: it is scanned for the appearance of Tooltip, and apparently also for a slot #2. And you would need to make the image roughly 3000. Because the number of sample points is always finite, however, it is possible that features of your function will sometimes be missed.

Theoretically, ContourPlot should start to resolve the roots with PlotPoints -> 3000 (x 0.0005 0.005 x 0.0005 0.005, interval length 3 3 ), maybe considerably less, but thats a prohibitive computation for my laptop. Both DensityPlot and ContourPlot use an adaptive algorithm that subdivides parts of the plot region to obtain more sample points for a smoother representation of the function you are plotting. To get a more controlled output we might add some modifiers such as.

which will draw level curves for zf (x,y) in the rectangle xmin,xmax × ymin,ymax in the xy-plane. The basic command for sketching level curves for a real-valued function of two variables in MATHEMATICA is. Here is what I think is going on with the second argument to ContourLabel.Įverything starts with the fact that ContourPlot has Attribute of HoldAll, which means that all the options you give it can be parsed in a non-standard way before being evaluated. I think I explained why ContourPlot failed. The 'ContourPlot' command in MATHEMATICA.
