To follow these instructions you will need:

(1) A Macintosh running MacOS 7.5 or later

(2) A program such as Stuffit Expander which can un-binhex a .hqx file.

(3) Matlab 5.X for Macintosh

(4) In certain special circumstances, you may need to have the MPW C compiler to compile Mex files.


1. Binary Download the file WaveLab0802.sea.hqx to your
   Macintosh. You will need about 5MB of disk space.
2. un-BinHex the file, creating the self-extracting archive
   WaveLab0802.sea
3. Double-click on the self-extracting archive and install it in the
   Toolbox folder of your Matlab folder.
4. Using Find File from the Mac Finder, determine if you have any
   files named startup.m (besides the one contained in Matlab:Toolbox:WaveLab) in the hierarchy rooted at Matlab. If you don't, skip to step 6.
5. If you do have more than one startup.m file, copy the contents of the
   startup.m in Matlab:Toolbox:WaveLab to the startup.m, and rename the one in
   Matlab:Toolbox:WaveLab.
6. Edit WavePath if your Matlab directory has a different pathname
   reference than the one supplied at the top of this file.

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 can be installed automatically by Matlab when you run Matlab if you have the MPW C compiler. To check if the process has worked, try the matlab command which FWT_PO. You should get the response Macintosh HD:Matlab:Toolbox:WaveLab:Orthogonal:FWT_PO.mex or something similar. If you get instead Macintosh HD:Matlab:Toolbox:WaveLab: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 from us. These can be installed manually, copying them into the appropriate locations. For example, the file FWT_PO.mex goes to Macintosh HD:Matlab:Toolbox:WaveLab:Orthogonal:FWT_PO.mex or something similar. 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.

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