upperContour

Measure upper contour of eye diagram

Since R2024a

Syntax

[time,amp] = upperContour(obj)

[time,amp] = upperContour(obj,index)

Description

[time,amp] = upperContour(obj) returns the upper contour of the eye diagram object obj.

[time,amp] = upperContour(obj,index) returns the upper contour of the eye diagram object obj at the eye opening specified by index.

Input Arguments

obj — Eye contour object

eyeContour object

Eye contour object, specified as an eyeContour object.

index — Index at which upper contour is calculated

scalar | nonscalar | logical vector

Index at which the function calculates the upper contour. The function indexes the lowest eye opening as 1.

Data Types: double

Output Arguments

time — Time coordinates for upper contour

matrix

Time coordinates for the upper contours of each eye in the eye diagram, returned as rows of a matrix. The first row corresponds to the eye opening with the lowest center amplitude.

amp — Amplitude coordinates for upper contour

matrix

Amplitude coordinates for the upper contours of each eye in the eye diagram, returned as rows of a matrix. The first row corresponds to the eye opening with the lowest center amplitude.
