DSP-First (and SP-First) MATLAB Files (Updated for MATLAB Ver 8.4, R2014b)

Latest release (24-Jun-2015): spfirst_v165.zip
Should work on all versions of MATLAB back to 7.2 (2006):

Installation Procedure to add these files to MATLAB and update MATLAB's path:
  1. Download the ZIP file that contains everything. It is called spfirst_vNNN.zip..
  2. Unzip spfirst_vNNN.zip somewhere. A good choice would be the directory: ...\MATLAB\toolbox\spfirst\. The unzip will create a bunch of subdirectories.
    NOTE: use forward slash for directories on Mac or Linux.
  3. Then add this one directory ...\MATLAB\toolbox\spfirst\ to the MATLAB path. This can be done in MATLAB from the menu File->Set Path.
  4. Next, type the command spfirst at the MATLAB comand prompt. It will add the other appropriate subdirectories to the path.
  5. Finally, under File->Set Path, do a save of the new path.
Once the MATLABPATH is correct, you should be able to type zdrill or sindrill at the MATLAB command prompt and have a GUI start up. Also, commands like zprint will now work.

UNinstall: Delete all the files and directories in ...\MATLAB\toolbox\spfirst\, and also manually remove the directories from MATLAB's path via File->Set Path.

FOOTNOTE: The M-files should be platform-independent, i.e., insensitive to end-of-line terminators for Unix/Mac versus Windows.
