[comp.edu] Parser for symbolic Mathematical Expressions

jjadamec@wpi.wpi.edu (Joseph M Jadamec) (10/19/89)

     I'm looking for a parser, either public domain, or one that can be obtained
for < $100.  I would really prefer one written in C.

     The parser is to be used on mathematical expresions involving variables
and symbolic functions like sin(x), cos(x), e^x, x^2,... in a Calculus 
tutorial/ drill&practice program.  

    If you have any information on such a parser, or know specifically where I 
could get my hands on one, please send your
response to:
jjadamec@wpi.wpi.edu
or
jjadamec@wpi.bitnet

thank you.
