vectline is "vector field line plotter". Depending on the dimension of coordinate axis, vectline can plot both 3D and 2D vector field line. Example for 2D field >> syms x y >> F = [-y, x]; >> vectline(F,[x,y],[-1,1,-1,1]) Example for 3D field >> syms x y z >> F = [x*y^2, x*y, z]; >> vectline(F,[x,y,z],[-1,1,-2,3,1,3]).

VECTGUI is an esay-to-use 3D vector field simulator with a friendly GUI. It can visualize the vector field, calculate divergence and also plot the curl of the field, all in one single GUI. All you need to do is to enter the symbolic expression for x,y and z component of the vector field, specify the ranges for x, y and z coordinates and push the Draw button. Example: >> vectgui % Simply opens GUI but does not return anything to workspace. >> H = VECTGUI; % Opens GUI and also returns a cell array H to workspace.

I spent some time working out how to export data from Matlab (specifically a 3D vector field) in a way which could then successfully imported into ParaView (www.paraview.org). I made this tutorial to summarize the method I found - which I hope others will also find useful..

The files in this package comprise two Matlab functions that create visualizations of 2D vector fields. cquiver renders a vector field as a grid of unit-length arrows. The arrow direction indicates vector field direction, and the color indicates the magnitude. Color is taken from the current colormap. vfcolor renders a vector field as a grid of colors. Hue indicates the field direction, and saturation indicates the magnitude. The current implementation uses a fixed color coding..

A vector field is a field which associates a vector to every point in the field space. Vector fields are often used in physics to model observations which include a direction for each point of the observed space. Examples are movement of a fluid, or the force generated by a magnetic of gravitational field, or athmospheric models, where both the strength (speed) and the direction of winds are recorded.

The effect of vector fields can be easily calculated by applying difference equations to all points of the observed space.

Vistools is a set of tools to easily visualize some scientific data, without need to learn difficult API, so you can see your 3d results very quickly. Also some sci tools for which we made it, including vector field tracing and simple optimization..

This function plots a slice of a 3D vector field by using the pixplot routine to denote the out-of-plane component. The magnitude of the longest vector arrow is displayed in the title. The function returns a handle to the title so it can be edited directly using 'get' and 'set' on it's 'String' property..

One of the few weak points in MATLAB is its low speed when displaying 3D vector plots. Paraview is an open source visualization tool that seems to work pretty well. This contribution shows how the MATLAB 3D flow example is written to a binary VTK file. In Paraview follow these steps: * CTRL+O to open the generated VTK file * Hit Apply in Object inspector * Click Glyph and hit Apply: The 3D vector field is displayed..
