- % This M-file is designed to be used in a Simulink S-function block.
- % It plots eyediagram against time and the scatter plot.
- % The parameter for the block of this figure are:
- %
- % timeRange Time range = [Digit Sample Time, Plot offset, Decision offset]
- % boundary Lower and upper boundary of the Y axis.
- % storeLength Keep number of traces in storage for print purpose.
- % eyeLine Line type for eye-pattern diagram (0 for no such plot)
- % scatterLine Symbol type for scatter plot (0 for no such plot)
- % sampleTime [Update sample time, update offset]
- %
- % This file takes scalar input or 2 dimensional vector input
- %
- % Set this M-file up in an S-function block.
- % Set the function parameter up as a four element vector
- % which defines the axis of the graph. The line type must be in
- % quotes.
