blockBode
Calculate quantities to plot Bode diagram
Information
This complex block is used to determine variables of a Bode diagram for the output y.
The output y is calculated by u / divisor if useDivisor == true.
Otherwise the output y = u.
abs_yAbsolute value ofyarg_yAngle ofydB_yLogarithm to the base 10 of the absolute value ofyin dB
