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.
The notion of matrices being âsimilarâ is a lot like saying two matrices are row-equivalent. Two similar matrices are not equal, but they share many important properties. This section, and later sections in Chapter R will be devoted in part to discovering just what these common properties are.uppose $A$, $B$ and $C$ are square matrices of size $n$. Then. $ 1 A$ is similar to $A$. ( 2 Reflexive). 3  If $A$ is similar to $B$, then $B$ is similar to $A$. ( 4 Symmetric). 5  If $A$ is similar to $B$ and $B$ is similar to $C$, then $A$ is similar to $C$.
