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.
Matrices and Arrays. Matrices and arrays are the fundamental representation of information and data in MATLABÂ®. You can create common arrays and grids, combine existing arrays, manipulate an array's shape and content, and use indexing to access array elements. For an overview of matrix and array manipulation, watch Working with Arrays.
