rifd	Examples See Also

Display the real, imaginary, frequency and damping ratios of a CONSTANT input vector

Syntax

rifd(vec)

Description

rifd displays the real, imaginary, frequency, and damping ratios of a CONSTANT input vector. The ith frequency is given by the

and its damping ratio is defined as real(sys(i))/(i).

Examples

Display the poles of the SYSTEM matrix, sys.

sys = pck(rand(4,4),rand(4,2),rand(1,4)); 
rifd(spoles(sys))
