Question

An ordered rectangular array of elements is called a mtric mostly we deal with matrices with elements being real numbers and comex

Answer 1

Answer:

Definitions

A matrix is a rectangular array of values. A single value is called a scalar. Matrices are denoted in text by bold faced often capitalized letters, as M, while scalars remain light faced. The numbers of rows and columns are its dimensions, symbolized (r, c), often written as subscripts on the matrix name, as M(r,c). The matrix contains r times c values, or elements. If one but not both of r or c is 1, it is a row or column matrix, usually called a vector. The matrix is displayed as the r×c array enclosed in brackets, as, for example, a matrix M(2,2) and a vector N(1,2):

M=[ 1 2 3 4 ] and N=[ 5 6 ].

The typical value of an element lying in the ith row and jth column is often denoted as the lower case scalar letter equivalent to the matrix’s name, as mij. For example, in M, m12=2. Alternatively, the typical element in brackets may be used to denote the matrix itself, as M=[mij].
