Engineering often involves applying a consistent, structured approach to the solving of problems.
A general problem-solving approach and method can be defined, although variations will be required
for specific problems.
Problems must be approached methodically, applying an algorithm, or step-by-step procedure by
which one arrives at a solution.
MATLAB® & Simulink® are the premier software packages for technical
computation, data analysis, and visualization in education and industry. The
Student Version of MATLAB & Simulink provides all of the features of
professional MATLAB, with no limitations, and the full functionality of
professional Simulink, with model sizes up to 300 blocks. The Student Version
gives you immediate access to the high-performance numeric computing power
Basic elements of program
– Initialize, define or assign numerical values to
Set of command expressions
– Operations applied to input variables that lead
to the desired result.
– Display (graphically or numerically) result.An example of technical computinAn example of technical computing
Let us consider using the hyperbolic tangent
to model a downhill
section of a snowboard
or snow ski facility.
Let us first examine the hyperbolic tangent
function by executing the command:
ezplot( ‘tanh(x)’ )...
Telephone and e-mail access to our technical support staff is not available for students running the MATLAB & Simulink Student Version unless you are experiencing difficulty installing or downloading MATLAB or related products.
There are numerous other vehicles of technical support that you can use. The “Additional Sources of Information” section in the CD holder identifies the ways to obtain support.
Building on MATLAB (the language of technical computing), Simulink provides a
platform for engineers to plan, model, design, simulate, test and implement complex
electromechanical, dynamic control, signal processing and communication systems.
Simulink-Matlab combination is very useful for developing algorithms, GUI assisted
creation of block diagrams and realisation of interactive simulation based designs. The
eleven chapters of the book demonstrate the power and capabilities of Simulink to
solve engineering problems with varied degree of complexity in the virtual
MATLAB (MATrix LABoratory) is an interactive technical computing environment for scientific and engineering applications. It integrates numerical analysis, matrix computation, signal processing, and graphics in an easy-to-use environment. By using its relatively simple programming capability, MATLAB can be easily extended to create new functions. MATLAB is further enhanced by numerous toolboxes such as the Signal Processing Toolbox.
Starting MATLAB on Windows Platforms
To start MATLAB on a Microsoft Windows platform, double-click the MATLAB
shortcut icon on your Windows desktop. The shortcut was automatically
created by the installer in the installation directory.
If you start MATLAB from a DOS window, type matlab at the DOS prompt.
After starting MATLAB, the MATLAB desktop opens – see Chapter 2, “Using
If you use a virus scanner, your settings may slow down MATLAB startup. For
example, if you use McAfee VirusScan, set the options to scan program files
When teaching technical subject lab works play an important role, as important as exercise sessions in helping students assimilate thoery. The recent introductions of simulation tools has created a new way to work, halfway be- tween exercise sessions and lab works.
You can define startup options for MATLAB, which instruct MATLAB to perform certain operations upon startup. There are two ways to specify startup options for MATLAB: • “Using the Startup File for MATLAB, startup.m” on page 1-5 • “Adding Startup Options for Windows Platforms” on page 1-5 or “Adding Startup Options for UNIX Platforms” on page 1-7
Using the Startup File for MATLAB, startup.m
At startup, MATLAB automatically executes the master M-file matlabrc.m and, if it exists, startup.m. The file matlabrc.
A purchaser should assess the environmental risks associated with
a property being purchased. In Canada, government o"cials do not
“certify” that a property is free from such risks. A property’s
environmental status can be ascertained by inspecting applicable
company and public records. In virtually all cases, a purchaser will
want to do an “environmental audit” of the property which may
include conducting scienti!c testing and a technical analysis of the
property. Lending institutions often require such an audit before
advancing any funds.
In the case studies, lack of institutional capacity and non-transparent processes that did not involve local
consultation led to overlapping land claims, conflict, and negative outcomes for local communities. Weak
land governance creates challenges to reigning in opportunistic behavior by elites, e.g. by ensuring proper
consultation with local and indigenous populations and makes it difficult to appreciate the true value of a
piece of land. In many cases this appears to have resulted in land being transferred at implicit values that
were well below its opportunity cost.
