    Syntax

    droots(zero,pole,gain)
    droots(zero,pole,gain,character)

    Description

    droots(zero,pole,gain) displays the transfer function.

    droots(zero,pole,gain,character)displays the transfer function in terms of the transfer function display variable, character. When Simulink® draws the block icon, the initialization commands execute and the resulting equation appears on the block icon.

    Input Arguments

    collapse all

    Zeros of the transfer function, specified as a cell array. Zeros are the values of the complex variable that make the numerator of the transfer function equal to zero.

    Example: [-4 -3]

    Data Types: cell

    Poles of the transfer function, specified as a cell array. Poles are the values that make the denominator of the transfer function equal to zero.

    Example: [-2 -3]

    Data Types: cell

    Gain of the transfer function, specified as an integer.

    Example: 4

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

    Display variable for the transfer function, specified as a string or a character vector.

    Example: z

    Data Types: char | string
