In mathematics matrix is rectangle shape of array of number, symbol and expressions which is arranged in columns and rows. Suppose the dimension of matrix is 2 x 3
we can say two by three because there are two rows and three columns. the individual item in a matrix are called entries or elements.
The size of matrix are depend by the number of rows and columns. which is P x Q, P defined as rows and Q defined as column.
Where as single row matrix called row vectors.
Row vector: 1 x n = [4 6 9]
The matrix which contain only one column are called column vectors.
Column vector: n x 1 =
The matrix which has same number of row and column are called square matrix.
square matrix: n x n =
In transpose of a matrix where all the rows of a given matrix turning into columns and viceversa. Suppose A is written as A^{T}
Addition or subtraction of a matrix are performed by adding or subtracting of corresponding elements of two given matrices. when two matrix are added or subtracted when they have the same dimension or they have the same number of row and columns. we consider of two matrices as matrices P and matrices Q.
In linear algebra a determinant matrix is obtained by the addition of product of the elements of a square matrix according to a given rule.
We have 3 x 3 matrix and we have some specific formula to obtain a determinant of a matrix.
Inverse of matrix is a matrix which change its position or swap the position.
We have written the inverse of A is A^{1}
