As of now this package only containts the uc.check function wich checks whether the roots of a given polynomial lie outside the Unit circle.
The function uc.check has the following Arguments:
| Argument | Description |
|---|---|
| pol_ | A vector of polynomial coefficients in increasing order. |
| plot_output | Logical that defines whether a graphical output should be created. |
| print_output | Logical that defines whether to print the results. |
library(UnitCircle)
uc.check(pol_ = c(1,0,0.99999), plot_output = FALSE)
#> real complex outside
#> 1 0 1.000005 TRUE
#> 2 0 -1.000005 TRUE
#> *Results are rounded to 6 digits.uc.check(pol_ = c(2,0,2.2,-3), plot_output = TRUE)
#> real complex outside
#> 1 -0.232289 0.708919 FALSE
#> 2 -0.232289 -0.708919 FALSE
#> 3 1.197912 0.000000 TRUE
#> *Results are rounded to 6 digits.
