print.bertini_posdim: Printing Positive-Dimensional Bertini Solution Sets

In dkahle/bertini: Interface to 'Bertini'

Printing Positive-Dimensional Bertini Solution Sets

Description

For positive-dimensional runs in Bertini, the most interesting output comes from the numerical irreducible decompositions. This printing method displays the most interesting information from the output to the screen. The two tables are the Witness Set Decomposition and the Decomposition by Degree.

Usage

## S3 method for class 'bertini_posdim'
print(x, ...)

Arguments

x	an object of class bertini_posdim
...	additional parameters

Value

Invisible string of the printed object.

Examples

if (has_bertini()) {

# see ?bertini

# solution set to xy = 0

# using bertini_input syntax
input <- bertini_input("x*y")
input <- modify_config(input, tracktype = 1)

# solution set: x and y axis in complex space (2 connected components)
bertini(input, output = "pos_dim")




# solution set to xz + y = 0, yz + x = 0

input <- bertini_input(c("x*z + y", "y*z + x"))
input <- modify_config(input, tracktype = 1)

# solution set: 3 lines (x=y=0 then z is free,
#                        x=y!=0 then z=-1,
#                        x=-y!=0 then z=1)

bertini(input, output = "pos_dim")
}
