  • 例程:DSP using MATLAB (Proakis)

    DIGITAL SIGNAL PROCESSING USING MATLAB By Proakis and Ingle, 1995 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.
