of digital elevation models from satellite data. h e continuing popularity
of the sot ware is also apparent in published scientii c literature, and many
conference presentations have also made reference to MATLAB. Universities
and research institutions have recognized the need for MATLAB training for
staf and students, and many earth science departments across the world now
of er MATLAB courses for undergraduates. h e MathWorks, Inc. provides
classroom kits for teachers at a reasonable price, and it is also possible for
students to purchase a low-cost edition of the sot ware. h is student version
provides an inexpensive way for students to improve their MATLAB skills.
h e following sections contain a tutorial-style introduction to MATLAB,
covering the setup on the computer (Section 2.2), the MATLAB syntax
(Sections 2.3 and 2.4), data input and output (Sections 2.5 and 2.6),
programming (Sections 2.7 and 2.8), and visualization (Section 2.9).
Advanced sections are also included on generating M-i les to recreate
graphics (Section 2.10), on publishing M-i les (Section 2.11), and on creating
graphical user interfaces (Section 2.12). h e reader is recommended to
go through the entire chapter in order to obtain a good knowledge of the
sot ware before proceeding to the following chapters of the topic. A more
detailed introduction can be found in the MATLAB
Primer
(MathWorks
2014a) which is available in print form, online and as PDF i le.
In this topic we use MATLAB Version 8 (Release 2014b), the Image
Processing Toolbox Version 9.1, the Mapping Toolbox Version 4.0.2, the
Signal Processing Toolbox Version 6.22, the Statistics Toolbox Version 9.1,
the Wavelet Toolbox Version 4.14, and the Simulink 3D Animation Toolbox
Version 7.2.
2.2 Getting Started
h e sot ware package comes with extensive documentation, tutorials and
examples. h e i rst three chapters of the topic
MATLAB Primer
(MathWorks
2014a) are directed at beginners. h e chapters on programming, creating
graphical user interfaces (GUIs) and development environments are aimed
at more advanced users. Since
MATLAB Primer
provides all the information
required to use the sot ware, this introduction concentrates on the most
relevant sot ware components and tools used in the following chapters of
this topic.
At er the installation of MATLAB, the sot ware is launched either by
clicking the shortcut icon on the desktop or by typing
