 FORMAL stands for &F&O&RTRAN &Matrix &Algebra &Library.
This library contains a number of subroutines
for performing matrix and statistical operations within FORTRAN
computer programs.
This library may be combined with FORTRAN statements in more
extensive programs. A &Simplified-&Restricted system has been devised
using the FORMAL procedures to provide students with minimal
or no knowledge of FORTRAN a means to obtain computations on matrix
problems for many class size problems and projects.
 This library allows the user to perform easy I/O (e.g., titles,
matrix printouts, scatterplots); matrix operations (e.g., matrix
eigen roots and vectors, inverses, Kronecker products); elementwise operations
(e.g., reciprocols or square roots of all elements);
matrix manipulations (e.g., copying matrices, concatenating or partitioning
matrices); and statistical operations (e.g., computing correlations,
factor analyses, simulations, ANOVA).
 Error messages are generated to assist debugging.
