Visualizes multivariate functions around a point or along a line between
two points in R^n
.

fn |
multivariate function to be visualized. |
x0,x1,x2 |
points in n-dimensional space. |
nlines |
number of lines to plot. |
npoints |
number of points used to plot a line. |
scaled |
scale factor to extend the line(s). |
fminviz
vizualizes the behavior of a multivariate function fn
around a point x0
. It randomly selects nlines
lines through
x0
in R^n
and draws the curves of the function along these
lines in one graph.
Curves that have at least one point below fn(x0)
are drawn in red,
all others in blue. The scale on the x-axis is the Euclidean distance in
R^n
. The scale
factor can change it.
flineviz
vizualizes the behavior of a multivariate function fn
along the straight line between the points x1
and x2
. Points
x1
and x2
are also plotted.
Plots a line graph and returns NULL
(invisibly).
