Question

What do you mean by matrix?

Answer 1

Matrix

• A matrix is the arrangement of elements into rows and columns to form an array.
• The horizontal arrangement is the row and the vertical arrangement is the column.
• In a matrix ${\left[A\right]}_{m\times n}$, there are $m$rows and $n$columns and the order of the matrix is $m\times n$.

• The position of elements is represented by $a_{mn}$. If the position of a number is $a_{43}$, then it is in the fourth row and third column.
