I used Mathcad generate the data pdf995 to generate the .pdf file. Mathcad can generate html files but Mathcad is so screwed up that all the links to the pictures use Microsoft back slashes instead of UNIX forward slashes so the html files don't work well with non Microsoft browsers. I have a love-hate relationship with Mathcad. It does some things extremely well ( symbolic math ) and other things are totally brain dead. Still it is a good deal if you can get a student version. I don't think I could have learned what I have without Mathcad or some other symbolic math package. Matlab and Scilab are good for getting answers. Mathcad is good for figuring out how that answer are derived symbolically.
