Chapter 4.8B, Problem 5GCE

To determine

Toexplain the thinking about the necessity of defining the list L3.

Answer to Problem 5GCE

L3 is important to define such that it can store the intermediate results.

Explanation of Solution

Given:

The List − matr function is used to define matrix [A].

Calculation:

Defining a list L3 is important as it is storing the intermediate results, if it is not defined the changes of the intermediate result will be lost. So it is important. It would have been possible to use $L1^0$ but the data saved in L1 can’t be retrieved later on which will be required for final finding of the polynomial.
