Syntax

plot(Hwav)
plot(Hwav,Name,Value)
plot(Hwav,Name,Value,LineSpec)
h = plot(___)

Description

plot(Hwav) plots the real part of the waveform specified by Hwav.

plot(Hwav,Name,Value) plots the waveform with additional options specified by one or more Name,Value pair arguments.

plot(Hwav,Name,Value,LineSpec) specifies the same line color, line style, or marker options as are available in the MATLAB® plot function.

h = plot(___) returns the line handle in the figure.

Input Arguments

Hwav

Waveform object. This variable must be a scalar that represents a single waveform object.

LineSpec

Character vector to specifies the same line color, style, or marker options as are available in the MATLAB plot function. If you specify a PlotType value of 'complex', then LineSpec applies to both the real and imaginary subplots.

Default: 'b'

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

PlotType

Specifies whether the function plots the real part, imaginary part, or both parts of the waveform. Valid values are 'real', 'imag', and 'complex'.

Default: 'real'

PulseIdx

Index of the pulse to plot. This value must be a scalar.

Default: 1

FrequencyOffset

Frequency offset

Frequency offset in Hz, specified as a scalar.

Dependencies

This property applies when you set the FrequencyOffsetSource property to 'Input port'.

Default: 0 Hz

Output Arguments

h

Handle to the line or lines in the figure. For a PlotType value of 'complex', h is a column vector. The first and second elements of this vector are the handles to the lines in the real and imaginary subplots, respectively.

Open Live Script

Create and plot a phase-coded pulse waveform that uses the Zadoff-Chu code.

waveform = phased.PhaseCodedWaveform('Code','Zadoff-Chu','ChipWidth',1e-6, ...
    'NumChips',16,'OutputFormat','Pulses','NumPulses',2);
plot(waveform)

Figure contains an axes object. The axes object with title Phase-coded pulse waveform: real part, pulse 1, xlabel Time (s), ylabel Amplitude (v) contains an object of type line.
