Fleishman, Ph.D. .tp 8.C; Lederle Laboratories .SP 1 .s 1 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.
