Origins of MATLAB and OctaveMATLAB

MATrix LABoratory ( MATLAB ).

Developed by Cleve Moler in the 1970s.

Purpose: teach matrix theory at University of New Mexico.

Origins of MATLAB and OctaveOctave

Octave is an open source (GPL) project that is similar to MATLAB

Developed by John W. Eaton in 1988 for chemical reactor designcourse

Named after his professor, Octave Levenspiel

What is MATLAB/Octave ?Characteristics of the language

Scripting language (not strongly typed), biased towards high precisionnumerical computations:

x=1 (defaults to 64 bit double)

Integrated development environment with debugger & compiler

Heavy use of linear algebra libraries

What are the advantages of using MATLAB/Octave ?Outline

Language syntax and libraries suitable for applying signal processingand linear algebra techniques

Graphics

Highly portable and very well documented

Strong user community

What are the advantages of using MATLAB/Octave ?Language syntax and libraries

Very concise and intuitive syntax for developing linear algebra andsignal processing algorithms:

y= Axx= A\y

Libraries for filter design, wavelets, control systems, neural networks,image processing, statistics ... etc

Ideal for quickly developing, testing, and cross validating

What are the advantages of using MATLAB/Octave ?Graphics

Easy to use and well documented graphics library
