DIGITAL SIGNAL PROCESSING USING MATLAB -------------------------------------- By Proakis and Ingle, 1995 MS-DOS Diskette Contents ------ -------- -------- The diskette contains all Matlab functions developed in the accompanying book. These functions, which can be treated as a new DSP toolbox, are available in the subdirectory "pws_dsp". This toolbox can be used either in book exercises or for general signal processing operations. Place this toolbox as a subdirectory in your Matlab Toolbox directory and place its reference in the MATLABPATH environment variable. This can be done by editing your matlabrc.m file in the MATLAB directory. This diskette also contains all Matlab script files used in Chapter Examples. These files are available in each chapter subdirectory. It is not necessary to reference each subdirectory in the MATLABPATH environment. The best approach is to make each subdirectory as a current directory (using the "chdir" command) when you want to use or modify scripts. Finally, some figures generated in the book using Matlab are also provided as script files for learning experience. These are available in the "figures" directory. The overall directory structure is as follows: DIRECTORY COMMENTS --------- -------- \CHAP_02 : Matlab script files: Chapter 2 Examples \CHAP_03 : Matlab script files: Chapter 3 Examples \CHAP_04 : Matlab script files: Chapter 4 Examples \CHAP_05 : Matlab script files: Chapter 5 Examples \CHAP_06 : Matlab script files: Chapter 6 Examples \CHAP_07 : Matlab script files: Chapter 7 Examples \CHAP_08 : Matlab script files: Chapter 8 Examples \FIGURES : Matlab script files for figures \PWS_DSP : DSP Toolbox containing Matlab functions : developed in the book. These M-files are User Contributed Routines which are being redistributed by The MathWorks, upon request, on an "as is" basis.
