Mat: An Interactive Calculator for Matrix Operations. Description and Application Examples

摘要

This report describes the commands, operators, and functions of mat-an interactive interpreter and calculator for solving systems of equations expressed as matrices. Also provided are examples that show how the system is used to solve problems in matrix algebra, input-output analysis, and regression analysis, mat features a full range of matrix and scalar operators and built-in functions for carrying out numeric and nonnumeric matrix transformations. It also provides checks for errors in conformability and other run-time problems.
