Definition of Matrix
Matrix is an arrangement of elements or entries in rectangular shape arranged in rows and columns.Matrix Order
The order or size of the matrix is the number of row elements followed by the number of columns. Amxn means matrix A has an order of m x n, meaning that the metric has m rows and n pieces of column.Example:
Answer:
Matrix A consists of 2 rows and 4 columns, the matrix A is 2 x 4, or Amxn.
Types of Matrices
3.1 Zero Matrix
The zero matrix is a matrix whose all elements are zero.Example:
3.2 Column Matrix
The column matrix is a matrix consisting of only one column.Example:
3.3 Row Matrices
Row matrix is a matrix consisting of only one line.Example:
3.4 Square Matrix
The square matrix is a matrix whose number of rows is equal to the number of columns.Example:
3.5 Diagonal Matrix
The diagonal matrix is a matrix whose entire element is zero except that the main diagonal is not always zero.Example:
3.6. Triangle Matrix
Triangle matrix consists of two kinds, such as:3.6.1 Top Triangle Matrix
The upper triangular matrix is a matrix whose elements below the main diagonal are entirely zero.
Example:
3.6.2 Bottom Triangle Matrix
The lower triangular matrix is a matrix whose elements above the main diagonal are all zero.
Example:
3.7 Identity Matrix
The identity matrix is a square matrix that all elements on the diagonal are primarily one and the other is zero.Example:
