Review of Mizzi 1971 view details Abstract: This paper describes the features of an elegant and powerful preprocessor for FORTRAN which extends the source language to vectors, matrices and arrays as elementary operands of the language, and performs numerical analysis on certain classes of problems to select preferred algorithms for the numeric solutions. These classes are matrix computations including systems of linear equations, both normal and overdetermined (where a least squares algorithm is applied), and ordinary and partial differential equations, including some non-linear simultaneous differential equations.

    The preprocessor uses formal manipulation of equations as in FORMAC to rearrange and simplify equations for solution, form derivatives, etc., and then supplies detailed FORTRAN declarations, and selects subroutines to efficiently evaluate the solution.

    Many convenience features are included, such as simplified input with implicit declaration of vectors and matrices, dynamic array declaration and release during execution and automatic plotting of results.
