Physicians routinely recommend a high-fiber diet that is full of roughage, or insoluble fiber, in order to keep things moving along. While this can be helpful, in some cases a high-fiber diet may actually promote intestinal infection. High-fiber diets are also high-residue diets.
The MATRIX program is designed to perform and to teach row operation algorithms on matrices. The program can work in a decimal floating-point mode in which calculations are carried out to 18 significant digits, or it can work in a fraction mode with exact rational arithmetic.
Using Matrix Data Types for 2D Graphics. First, you need data types for the matrices you'll be using in your programs. Programs that deal with 2D graphics typically use two types of matrices: 1x3 and 3x3. The 1x3 matrix is a special type of matrix known as a vector. Vectors can represent a vertex in a shape, by holding the vertex's X, Y, and W values.
