1. Binary Download the archive to, for example, /tmp.
2. Uncompress the archive: uncompress WaveLab0802.tar.Z
3. Decide where you want the WaveLab directory to reside. It will have
   a number of subdirectories and occupy at least 5 MB disk space.
4. cd to the place you want the directory to reside
5. tar xvf <WaveLabTarFile>, where <WaveLabTarFile> should be
   the absolute pathname of the WaveLab0802.tar archive, for example
   with the /tmp prefix if necessary.
6. After you de-tar the file for your machine, you should have the
   following directory structure:

7. Edit the file WavePath.m, put the lines
   if strcmp(Friend,'<YourMachineType>'),
   WAVELABPATH = '<AbsolutePathNameforWaveLabMainDirectory>' ;
   PATHNAMESEPARATOR = '<YourMachine*sPathSeparator>';
   end
   in the appropriate place (this will be evident). Here {\tt Friend} has been
   predefined by the \Matlab\ command Friend = computer; Also, WAVELABPATH names the place where WaveLab will reside. For an individual user without root privileges, a good choice is ~<USERLOGIN>/matlab/WaveLab, where <USERLOGIN> is the user's account name. For a system manager with root priveleges, a good choice is <MatlabToolBoxPath>/WaveLab, where <MatlabToolBoxPath> is the name of the directory containing all the Matlab toolboxes.
   
8. Copy all the wavelab files from the place you put the original Wavelab archive (for example /tmp) to their final destination as named in the variable WAVELABPATH, for example in your home directory ~user/matlab/WaveLab.
9. In the matlab subdirectory of your home directory, put a copy
   of the files startup.m and WavePath.m, both from the directory named above
   in WAVELABPATH.
   
10. At this point check that you have a working system. Launch Matlab. It should now start up with a banner indicating that WaveLab 800 is installed. Try running a script, such as SCDemo, to see if it will run. If it does not, recheck all the above steps

Many of the basic routines in WaveLab can be accelerated by the use of Mex files. These are binaries of routines coded in C and run in some cases 10 times faster than their .m counterparts. They will be installed automatically by Matlab when you run Matlab if you have permissions to write the files in the correct places. Hence if you are system manager, you should run Matlab at least once after WaveLab has been installed in order to perform theinstallation procedure. To check if the process has worked, try the matlab command which FWT_PO. You should get the response <WAVELABPATH>/Orthogonal/FWT_PO.mexlx or something similar. If you get instead <WAVELABPATH>/Orthogonal/FWT_PO.m -- note the .m suffix rather than .mex??? -- start troubleshooting.

If you cannot get the MEX files to install automatically, you can download mex files for certain platforms from us. These can be installed manually, copying them into the appropriate locations. For example, the file FWT_PO.mexsg64 needs to be copied to <WAVELABPATH>/Orthogonal/FWT_PO.mexsg64. In general, each mex file needs to be in the directory of its homologous .m file.

If you are unable to get the .mex files to work at all, don't worry -- WaveLab will still work, but more slowly.

Compare the output of ls -r WaveLab with Documentation/WLFiles to see if you have all the files. Compare the output of the Matlab command path with the list above to see if you have all the
directories in your path.

When you have a successful installation, you should see something like the following when you invoke Matlab:

Commands to get started: intro, demo, help help
Commands for more information: help, whatsnew, info, subscribe
