Version 1.1 was released in December of 1991. It was a bit of
rush job. The new version fixes some of the problems and adds
the graphics object. D.1 The
improvements include
- A graphic object for X-Y plots. This requires Borland
graphics interface files.
- A 15 to 20 percent speed improvement using a deep-copy
trick on the stack. The stack now stores references
to the vectors in virtual matrices instead of copying
the matrix.
- An Index function for generating index matrices.
- Important, The virtual matrix copy constructor
performs garbage collection by calling cleanstack().
This means functions that use copy constructors
should also call Inclevel() before using
the copy constructor.
- Some bugs were fixed in the string operators '+'.
The names in Mexp, Mlog, Mabs, etc were fixed.
The make files work now for building a Borland
library. I also got sloppy and left out some
documentation files.
