Answer 1

Answer:

Step-by-step explanation:

Different types of Matrices and their forms are used for solving numerous problems. Some of them are as follows:

Types of Matrices

1) Row Matrix

A row matrix has only one row but any number of columns. A matrix is said to be a row matrix if it has only one row. For example,

A=[−1/2√523]

is a row matrix of order 1 × 4. In general, A = [aij]1 × n is a row matrix of order 1 × n.

2) Column Matrix

A column matrix has only one column but any number of rows. A matrix is said to be a column matrix if it has only one column. For example,

A=⎡⎣⎢⎢⎢0√3−11/2⎤⎦⎥⎥⎥

is a column matrix of order 4 × 1. In general, B = [bij]m × 1 is a column matrix of order m × 1.
