Abstract: MATRIX.BYU is a general purpose Fortran program for personal computers which provides a flexible and user friendly platform for the input and output of matrix data, the execution of standard and special matrix operations, and the creation of application programs. Access to the capabilities of the program is contained in a hierarchy of menus. At the higher level, the user may select access to the input/output options, the matrix operations, or the applications programs. Second level menus specify the available options in each category. Examples presented include the least-squares fit problem, the analysis of trusses, and the calculation of natural frequencies and associated mode shapes.
