Check if Roots of a Polynomial Lie Outside the Unit Circle
Description
This function outputs the roots of a given polynomial. It also checks whether they lie outside the unit circle and creates a plot to illustrate the results in an intuitive way.
Usage
uc.check(pol_, plot_output = T, print_output = T)
Arguments
pol_ |
the vector of polynomial coefficients in increasing order. |
plot_output |
Logical that defines whether to create a plot. |
print_output |
Logical that defines whether to print the results. |
Examples
uc.check(pol_ = c(1,0,0.999999999), plot_output = FALSE)
uc.check(pol_ = c(2,0,2.2,-3), plot_output = TRUE)
