# Diagonal Matrix Calculator

Matrix is a grid function that has an ordered rectangular array of numbers. The numbers present in the array are called entities. The numbers are arranged in rows and columns. The vertical arrangement is called columns and the horizontal arrangement of numbers is called rows. In a diagonal matrix, all the elements except the elements along the diagonal are zero.

## How to Find a Diagonal Matrix?

In a given [m×n] matrix if all the elements except the one along the diagonal are zero (i.e. a_{ij} = 0 when i ≠ j) then the given matrix is known as a diagonal matrix. Therefore, it should follow the condition:

**a _{ij} = 0 when i ≠ j**

**Solved Example:**

What should be the value of a, b, and c or the given matrix A to be a diagonal matrix?

**Solution:**

For a matrix to be a diagonal matrix it should follow the condition

a_{ij} = 0 when i ≠ j

So, a = b = c = 0

Thus the value of a, b, and c will be 0 for the matrix A to be a diagonal matrix.
