quiver(U,V)
quiver(X, Y, U, V)
quiver(…, scale)
quiver(…, LineSpec)
quiver(…, LineSpec, 'filled')
Graph of velocity of the vectors with components (u, v) in the points (x, y). You can
define a scale, specifications, line and fill.
ribbon(y)
ribbon(X, Y)
ribbon(X, Y, width)
Graphic with three-dimensional tapes as columns.
Graph X against the columns of Y.
Specifies the width of the tape.
stairs(Y)
stairs(X, Y)
stairs(…,LineSpec)
Stairstep graphic with elements of Y.
Stairstep graphic with elements of Y corresponding with X.
When the LineSpec parameter is used, colors can be controlled using 'r'=red, and
so on.
scatter(X,Y,S,C)
scatter(X,Y)
scatter(X,Y,S)
scatter(…, marker)
scatter(…, 'filled')
Dispersion for the vector graph (X, Y) according to color C and the area of each
marker S. You can also get the graphic filled (fill option) and use different types of
markers.
scatter3(X,Y,Z,S,C)
scatter3(X,Y,Z)
scatter3(X,Y,Z,S)
scatter3(…,marker)
scatter(…,'filled')
Graphic three-dimensional scatter (X, Y, Z) vectors according to the colors C and
the area of each marker S. You can also get the graphic filled (fill option) and use
different types of markers.
TRI = delaunay(x,y)
Delaunay Triangulation.
K = dsearch(x,y,TRI,xi,yi)
Delaunay Triangulation for the nearest point.
IN = inpolygon(X,Y,xv,yv)
Detects points inside a polygonal region.
polyarea(X, Y)
Area of the polygon specified by vectors X and Y.
tsearch
Delaunay Triangulation.
voronoi(x,y)
voronoi(x, y, TRI)
Voronoi diagrams.
As a first example, we carry out a stacked area chart (see Figure
4-17
).
>> Y = [1, 5, 3;
