How can I plot Distance in 3D (using i,j,m) ?

[Jan]

We cannot run your code. degtorad and Antenna_X_Pos etc are not known.

what kind of 3D visualization do you want?

[zozo]

sorry..I have made the required changes. Now the code works!

How can I plot and view all coordinates of Distance vector?

[Jan]

The output "Distance" is a [8 x 360 x 90] array. How do you want to visualize this? As surface, as 3D-polar-plot, as set of 8 discs with different colors?

[zozo]

Can u tell me all the above mentioned types?

Coz I am not sure which one is best right now.

[zozo]

please suggest me matlab syntax to plot the above vector

[Jan]

Dear zozo, the variable "Distance" is not a vector, but a [8 x 360 x 90] array. It is not trivial to plot it and I will not post examples for all possibilities - there are too many.

Please take the time to find out, how you want to display these data. You can draw a picture by hand and post it.

[zozo]

Dear Simon,

surface plot is what Iam looking for.

[Walter Roberson]

You cannot surface plot an 8 x 360 x 90 array. The closest you can come is to use isosurface()

[zozo]

thank you @walter

If you store your distance data as 3D array 8 x 360 x 90 you have several ways to visualize what it looks like.

Both of these solutions turn 3D scaler fields into voxels with color and transparency, thus allowing you to visualize 3D density or distance fields.

Solution 1: Volumetric 3 is a full matlab application for visualizing layered 3D density matrices. It was designed to work with fmri and mri but it can handle arbitrary 3D arrays stored as .mat files.

Solution 2: A much simpler tool is Vol3D. But with a lot of programming on your end you can get it to do pretty much anything volumetric 3 does, in that they use highly similar (though distinct) techniques for generating visualizations.
