SUMMARY

Table A.1 of Appendix 1 lists all the arithmetic operations and their execution as matrix operations, each with an example.

Table A.2 again lists the arithmetic operations and their execution as field operations.

ON THE CD The MATLAB demonstration program aritdemo.m in the accompanying software illustrates the different possibilities associated with arithmetic operations. In particular, it provides practical experience with the difference between matrix and field operations and with the matrix concept in MATLAB. It can be started ⁷ by copying aritdemo to the command window.

PROBLEMS

Work through the following problems for practice with arithmetic operations.

NOTE Solutions to all problems can be found in Chapter 4.

	Problem 8 Start the MATLAB demonstration program aritdemo.m by calling the command aritdemo in the MATLAB command window and work through the program.
	Problem 9 Calculate the standard scalar product of the vectors using a matrix operation and a field operation, the product of the matrices using a suitable field operation calculate the matrix from the matrix
	Problem 10 Test left division with the matrix and the vector and interpret the result.
	Problem 11 Test right division with the matrix and the vector and interpret the result.
	Problem 12 Calculate the inverse matrix of using right (or left) division.
