Ander Biguri What does that mean? Throw us a bone here, we cant solve a problem with a line and a half of explanation. Post some minimal working example with what you get and what you want.

Yes it doesn't work!! Look, I have a vector field in excel file. So far so cool, right?

Important Announcement

Yes It doesn't work. And this is the error: Subscript indices must either be real positive integers or logicals. OK, now we have more information we can work with.

Please, edit your question with your new information. Active Oldest Votes. Your problem is basic understanding of Matlab. And clearly, 0 is not a real positive integer. Ander Biguri Ander Biguri You are right. I found a similar example on mathworks but I just can't understand the system of numbers. The error you have now is because you havent run the piece of code you showed me. The error is because the variable doesnt exist yet. I hihgly recomend you to do some matlab tutorials before ansking in stackoverflow, to ensure you have some basic understanding a priori.

I appreciate your help and information, but I don't think this webpage is only for professionals. It has a section where it says ask a question which means if you don't know something, ask it here. Thank you again for the time you spent. At least you need to show that you googled it. Tens of questions are closed every day just because the OP did,t do basic research. Read: stackoverflow.

Note: You can execute the code from this tutorial by highlighting them, right-clicking, and selecting "Evaluate Selection" or hit F9. This is based on a video tutorial on Doug's Video Tutorial blog. In this section, you'll learn how to visualize vector fields. Vector fields contain vector information for every point in space.

For example, air flow data inside a wind tunnel is a vector field. In order to visualize vector fields, you can use the quiver3 function. For 2D, use quiver. For this reason, the visualization may not be very useful if you want a higher resolution:. In such situations, there's a different function called coneplot that you can use. This way, you can work with a high-resolution data without sacrificing graphics.

A couple of other vector field visualization tools to keep in mind are streamtube and streamribbon. See the documentation for more information.

How to plot streamlines of 3D vector field? David Tschan on 2 Dec Vote 0. I want to plot the streamlines of the 3D vector field of the electric field of a static charge distribution.

The field is calculated using Coulomb's law. The code works fine, it gives the desired vector field using quiver3, no problem there. However, it fails to compute the streamlines of the vector field. When I run the code below, I get the error message: "Error using gridedInterpolant.It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in common mathematical notation. MATLAB has extensive facilities for displaying vectors and matrices as graphs, as well as annotating and printing these graphs.

It includes high-level functions for two-dimensional and three-dimensional data visualization, image processing, animation, and presentation graphics. In this tutorial we will use the command interface to show how to visualize scientific data using MATLAB graphics commands.

We will cover major visualization techniques such as slicing, color mapping, contouring, oriented glyphs, and streamlines. The most effective way for you to go through this tutorial is to run the listed example code in a MATLAB session as you proceed through the tutorial. It will also be helpful for you to browse the MATLAB documentation for the specific functions as we discuss them links are provided.

After browsing the documentation, you should then experiment with the example code by varying some of the arguments and watching the effect this has on the output. By playing with the example code, you will gain a deeper understanding of how the various graphic functions work. This will tell you on what machines MATLAB is available, how to set up your environment, how to set your display, and where the documentation is. This insures cross-platform portability and creates a device independent graphics layer.

Core graphics objects include basic drawing primitives such as line, text, rectangles, patches filled polygonssurfaces 3D grid of verticesimages 2D matrix representation of an imagelight sources, and axes define the coordinate system. Composite graphics objects are composed of core graphics objects that have been grouped together to provide a more convenient interface. In order to visualize your data, you will need a graphics window which contains a figurean axesand a view.

This window is referred to as a figure. Figures can contain menus, toolbars, user-interface objects, context menus, axes, or any other type of graphics object.

If a figure does exist, then these functions will display their graphics output in the current figure window the last figure window used or clicked in. By default this will be done without clearing or resetting the current figure properties. To create a new figure, use the figure function.

Here is example code to create a simple graphics window:. Every graphics object has a set of properties associated with it.Documentation Help Center. The arrays XYand Zwhich define the coordinates for UVand Wmust be monotonic, but do not need to be uniformly spaced.
