Describes how Suffern (New York) High School creates its master class schedule using a computer-generated "conflict matrix" that shows the enrollment for each course and the number of students who would experience scheduling conflicts if any two courses were offered at the same time. (Author/RW)

Computational and plotting problems are often encountered with the Johnson-Neyman analysis of covariance procedure (P. Johnson and J. Neyman, 1936) when using three covariates. Use of an appropriate design and contrast matrix for the general linear model and the Mathematica software system to overcome these problems is described. (SLD)

How to use the electronic spreadsheet (e.g., VisiCalc) creatively is discussed, with computer printouts for a number of algorithms. (MNS)

This article gives an overview of the new field of complexity theory which links computer science to mathematics, and ultimately to the solution of theoretical as well as practical problems in society and technology. (Author/MK)

A general description of microcomputer-based spreadsheet software capabilities and their usefulness in library management analysis and planning are presented. Five specific spreadsheet models which apply to retrospective conversion cost and scheduling, COM and book catalog costs, and acquistions processing costs are discussed and displayed in…

Presents computer programs (Applesoft Basic) for: (1) 2-D rotation about any point through any angle; (2) matrix transformation for 2-D rotation; (3) 3-D translation; (4) 3-D rotation; and (5) hyperboloid rotated in 2-D space. Includes background information and sample output for the matrix transformation subroutines. (JN)

The article discusses the use of computers to teacher college level mathematics. In particular, the Gaussian elimination procedure for solving a system of n linear equations in n unknowns, using a computer, is examined. (PK)

Provides a program listing in True BASIC which constructs several kinds of matrices: (1) matrices with integral entries that have inverses that have integral entries; (2) matrices with integral entries that have inverses that are rational numbers with reasonable denominators; and (3) matrices with integral entries and prescribed integer…

Reviews for three software packages are given. Those packages are: Linear Algebra Computer Companion; Probability and Statistics Demonstrations and Tutorials; and Math Utilities: CURVES, SURFS, AND DIFFS. (PK)
