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.
Create a matrix. A matrix is a rectangular set of numbers that are arranged in multiple rows and columns. Code a matrix by listing a series numbers separated by spaces or commas per row within the command window. For a new row, a semi colon is placed between the values of the old row and new row.
