Second Edition, January 2014

Image formats: Vector vs Raster

Raster graphics or bitmap

Vector graphics or line art

Figures in Matlab

manipulating and displaying graphics

display graphs and GUI components

◮ Unique identifier, called a handle

◮ Set of characteristics, called properties

plot function

Calling the plot function creates graphics objects:

function

Main functions for working with objects

Sinusoidal function

y=sin(t)

\includegraphics[width=2.5in]{sin1}

Problems:

Figure size

What is the size of your presentation?

For a beamer slide: width=5.04 in, length=3.78 inWhat is the desired figure size?

Labels and legend

Labels can have different font sizes

Labels, legend, and LATEX commands

Labels and legend

Mathematical writing is corrected

Figure has large white boundaries

Fonts are not proportional to the values we want

y = sin(t)

How to save the plot

Don’t export the plot to eps

Use print command to generate eps filesprint -depsc2 myplot.eps

Main vector formats

Exported eps vs printed eps

Exported eps

-1.5 -1 -0.5 0 0.5 1 1.5 2

-1 -0.5 0 0.5 1 1.5 2

Time(s) Sinusoidal function

y = sin(t)
