What is the Matrix?

The matrix in mathematics is the rectangular range, arranged into columns and line numbers, symbols and expressions. The size of the matrix is 2 to 3 for example, since there are two rows and three columns: if they are of the same size, the element can be added to or subtract from two matrices.

ROW MATRIX

If a Matrix have only row then it’s called Row Matrix

[7 4 6] is a Row Matrix

[51 21 31] is a Row Matrix

COLUMN MATRIX

COLOUMN MATRIX

NULL MATRIX

Null Matrix is the matrix containing only 0 number.

I = [ ], P = [ ]

DIAGONAL MATRIX

Defined as a square matrix, where all zero elements from the top left diagonally to the bottom left.

 

IDENTITY OR UNIT MATRIX

The diagonal elements are just one’s.

ADDITION AND SUBTRACTION OF MATRICES

Matrices in the same order are added (or subtracted) by adding (or subtracting) the respective elements in each matrix.

ADDITION AND SUBTRACTION OF MATRICES

 

A+B = B+A: A and B will change location when added.

(A+B) + C = A + (B+C): order of operation bracket first.

 

A – B ≠ B – A: A and B do not shift roles when subtracting.

MULTIPLICATION OF MATRIX BY A REAL NUMBER

MULTIPLICATION OF MATRIX BY A REAL NUMBER

Matrices can only be multiplied only if they are compatible. They become consistent because the number of rows of the second matrix is the same as the number of columns of the first matrix.
