Question

To indicate that 'A' is a matrix of order m × n we shall follow the notation

Options

• A = `[a_ÿ]_(n  xx m)`

• A = `[a_(ji)]_(m  xx n)`

• A = `[a_ÿ]_(m  xx n)`

• A = `[a_(ji)]_(n  xx m)`

Answer 1

A = `[a_ÿ]_(n  xx m)`

Explanation:

(i) We shall follow the notation, namely A = `[a_ÿ]_(m  xx n)` to indicate that 'A' is a matrix of order m × n

(ii) We will only consider matrices whose elements are real numbers or functions with real values.
