I am tring to write an application which requires the parsing of a user
defined mathematical operation, writen in standard mathematical
notation, for both vector and scalar values, into a line of code.
--vectors a b c
--scalars e f g
--input--->ans = (f*(a.b)+e*g)*c
should be transformed to a string such that:
--output--->ans = VecScalarMult(c,(f*(VecScalarProduct(a,b)+eg))
Where VecScalarMult and VecScalarProduct are functions
Does anyone have experience of this type of parsing, or do you have any
suggestions for where I could find info?
[Unless there's something I'm missing here, this looks like a straightforward
infix to prefix conversion, covered in any intro compilers text. -John]
