The Wolfram Language also has commands for creating diagonal matrices, constant matrices, and other special matrix types. Different types of Matrices and their forms are used for solving numerous problems. Special Utility Matrices; Famous Matrices. c) 9.2 SPECIAL TYPES OF MATRICES 9.2.1 SQUARE MATRIX A matrix having the same number of rows and columns is called a square matrix. A matrix can be entered directly with {} notation: You can show the result in matrix notation with MatrixForm: expr//fun is another way of entering fun [expr]. It is important to note that for any m-by-m matrix B, BIm = Im B = B. The matrix A is [x – sqrt 2009 , -1] [1, x + sqrt 2009].The determinant of this 2×2 square matrix is: a1*b2 – a2*b1=> (x – sqrt 2009)(x + sqrt 2009) – (-1)*1As the determinant is equal to 0(x – sqrt 2009)(x + sqrt 2009) – (-1)*1 = 0=> x^2 – 2009 + 1 = 0=> x^2 – 2008 = 0=> x^2 = 2008This gives the values of x as sqrt 2008 and -sqrt 2008The values of x are sqrt 2008 and -sqrt 2008 Deﬁnition.
