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
