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.
matrix algebra-the part of algebra that deals with the theory of matrices. diagonalisation, diagonalization-changing a square matrix to diagonal form (with all non-zero elements on the principal diagonal); the diagonalization of a normal matrix by a unitary transformation.
