Ex — Software for Numerical Computation in Native Oberon

“Ex” is the name of a library of software modules from which one can rapidly develop prototype or production versions of efficient numerical-computation application programs in the Native Oberon programming environment. Mathematical constructs that can be represented and processed by use of Ex modules include both integer and non-integer rational, real, and complex numbers; vectors; matrices; and the arithmetic, algebra, and calculus of the aforementioned quantities.
