Abstract Ex-Cog (Expression-Code Generator) is a flexible, generic code generator for java and other programming languages. A Ex -COG user can deft ne the mathematical functions by formulating _them usin~ the m.built functions of Ex-COG Altemarively, the user can use the defined formulas in the fonn of images.
