Syntax
zplane(a)
zplane(a, b)
Description
Plots zeros and poles.
Inputs
| Name | Description |
|---|---|
| a | Specifies the zeros to plot. If a is a row vector, the zeros are the roots of a polynomial whose coefficients, in decreasing order of power, are a. If a is a column vector, the zeros are the values in a. If a is a matrix, the zeros are the values in each column of a. LabVIEW plots the zeros in different columns of a with different colors. If a is a row vector and you do not specify b, the pole is (0, 0). If a is a column vector or a matrix and you do not specify b, LabVIEW does not plot poles. |
| b | Specifies the poles to plot. If b is a row vector, the poles are the roots of a polynomial whose coefficients, in decreasing order of power, are b. If b is a column vector, the poles are the values in b. If b is a matrix, the poles are the values in each column of b. LabVIEW plots the poles in different columns of b with different colors. |

Examples
A = [-1, 2, 0; -1 + 0.2i, 2 + 0.5i, 0; -1 - 0.2i, 2 - 0.5i, 0];
B = [-0.5 + 0.5i, 1; -0.5 - 0.5i, 1];
