I have 3 column vectors:

phi contains the number of radians from the North Pole

theta contains the number of radians from the Greenwich meridian

D contains number data corresponding to the point (phi,theta) on the sphere.

 

How do I plot:

a) a contour plot on the surface of the sphere where each point at (phi, theta) has a corresponding data value D?

b) a plot where the height above the surface at (phi, theta) is some linear function of D such as radius*D*constant?

Suppose i have an mx3 matrix M containing a 3D data where 1,2,3 columns are x,y,z coordinates.

Here is what i tried,

Statistics:-SurfacePlot(M[..,1],M[..,2],M[..,3]) does not produce what i want.

plots:-surfdata(M) plots what i want but only works when i use subset of the data for all the data it just hangs.

Statistics:-ScatterPlot3D(M, lowess, fitorder = 2) produces a smoothened version but i want the interpolated plot.

Please help. Here is one sample of the data i want to plot, Mdata.xlsxMdata.xlsx

 

Hi My main problem is that the new installer is ridiculously small that I cannot even press the buttons acuratley. I am running windows 8.1 on a Surface Pro 2. I had no problems installing maple 17.

 

I also ran into errors using the Bitrock installer 3 times, I am not even sure if it is installed correctly now.

 

is there anyway to get maple 18 without using the Bitrock installer?

Hi,

I have a file with arbitrary points which I want to connect with a surface. I have seen similar problems on this site but I can't fix my problem with the answers that are given, mainly because my points are just plain vectors. Can anybody help me? 
These are my points/vectors:

v1 := `<,>`(15, 6, 14.89);
v2 := `<,>`(15, 8, 14.72);
v3 := `<,>`(15, 10, 14.79);
v4 := `<,>`(15, 12, 14.95);
v5 := `<,>`(15, 14, 15.17);
v6 := `<,>`(15, 16, 15.43);
w1 := `<,>`(15/2, 4, 9.78);
w2 := `<,>`(15/2, 6, 9.95);
w3 := `<,>`(15/2, 8, 9.85); 
x1 := `<,>`(15*(1/3), 4, 8.71);
x2 := `<,>`(15*(1/3), 6, 8.44);
y1 := `<,>`(15/4, 4, 8.31); 

I can only plot the different points with 

with(plots);
pointplot3d({v1, v2, v3, v4, v5, v6, w1, w2, w3, x1, x2, y1}, scaling = CONSTRAINED, symbolsize = 20, color = red, axes = normal, labels = ["L/h", "n", "kg/m"]);

I hope someone can help me!

Does anyone has any maple worksheet that generate surface using the PDE method described in this article?  I am trying to learn this method but I am not familiar with the mathematics to do it although the paper gives some description of it.  I hope someone can demonstrate the procedure in Maple.  Thanks

Hi!

i have problems with surfdata command. I want to see beautifull surface, but see only few black lines.

and i dont know why, because i do all like in example.

 

Thank you vwry much for answers)

So I have the energy of an ion at a several points in space, where the x and z coordinates have been varied from 0-1, keeping y constant. The data is in the following file: 

y=0.xlsx

 

When I come to produce a 3D surface plot (grid) of this file using the plots option in the context menu (on right clicking), the following is produced: the x-axis is in red and the y-axis (z-coordinate) is in blue.

Yet if I use the interactive plot builder, to plot the same data, the only option available to me is a 3D point plot, which produces the following:

[If I try to plot a 3D surface plot (points) using the context menu, I get stuck at a evaluating stage...]

as, ideally, I want a surface plot, why, in the surface plot (grid) is MAPLE not recognising the data that corresponds to the higher z-coordinate values and how I can produce a full surface plot... 

@Carl Love

This is the integral

I do it by hand the result is Pi, but I do it with maple VectorCalculus it is zero,

how to do it fairly? please demonstrate.thanks!

How can I find the surface area of a normal chicken egg? http://math.stackexchange.com/questions/407310/how-can-i-find-the-surface-area-of-a-normal-chicken-eggPlaying replies to the topic in Mathematics Stack Exchange:_SurfaceAreaChickenE.zipGracias to Acer and Carl Love for your answers.

plot part of the surface f(x,y)=10-x^2-3y^2:

plot3d(10-x^2-3y^2, x=-1 .. 4, y=1 .. 2, view=0 .. 11, axes= normal); (press enter)

 

Determine the normal vector and the equation of the tangent plane at the point (2,1,3) on the surface.

Display the surface , a black vector and the tangent plane, and give the equation for each of them

label the normal vector and the tangent plane, and give the equation for each of them

 

Could you tell me how to write the following surface integral in Maple, please?



Hi there i have function as:

f(B,F)=

where: F,B>0 and 

,

such that: 

h=B^2;

I need to plot the surface (contour plot) f(B,F) at 0 and -ve points i.e f(B,F)<0.

Thanks

Dear Maple users

I know how to plot surfaces in 3D. However now I have a special task: I want to plot a piece of a solid region in 3D, more precisely a transverse or logitudinal wave. I wonder if there is an easy way to do this in Maple? Any hint will be appreciated!

 

Regards,

Erik

Maybe I'm missing something but I thought boys surface was one surface and when I plot it in maple it appears to have two surfaces.


I want to graph the portion of the plane 2x + 3y + z = 6 that are located in the first octant of a xyz coordinate system. The following implicitplot3d should in principle do it:
