A brief introduction to the scientific software package MATLAB is contained in this appendix. Further information is available at the web site www.mathworks.com. MATLAB is a scientific computation and data presentation language.
The chief advantage of MATLAB is its use of high-level instructions for matrix algebra and built-in routines for data processing. In this appendix as well as throughout the text a MATLAB command is indicated with the typewriter font such as
end. MATLAB treats matrices of any size (which includes vectors and scalars as special cases) as elements, and hence matrix multiplication is as simple as
B are conformable matrices. In addition to ...
