Interval Bode Plot

Plots the bode plot for an parametric uncertain system

The script plots the envelope of the bode plot for a parametric uncertain/interval system.

interval_bode(NumVec,DenVec,clr)

The function accepts the numerator (NumVec) and denominator (DenVec) of the uncertain system as matrices of two rows each. The first row containing the lower bounds and the second row with the upper bounds. The argument clr is for the optional filling colour.
