- WELCOME TO THE MATRIX DEMO
-
-
- The Matrix demo visualizes a 3D data set in several
- different ways:
-
-
- o Velocity field
- Each arrow represents a vector. This type of
- plot can be used to show ice displacement,
- slope gradient, oceanic current and more.
-
- o Contour plot
- The lines connect data items with equal values.
-
- o Image
- The X and Y coordinates correspond to the value
- indicated by the axes. The Z coordinate is
- represented by the color.
-
- o Surface plot
- The data values are shown in perspective,
- giving a three dimensional view of the data set.
-
- o Show3
- This combines 3 different representations
- of the same data set. The top has a contour
- plot. The bottom has an image plot. In the
- middle, there is a surface mesh.
-
- The plot is drawn with the simple command :
-
- SHOW3, data
