For two or more matrices to be equal they must have the same order and their corresponding array elements must be equal.

If we have two equal matrices:

Matrix A

2×2 |
Column 1 |
Column 2 |

Row 1: |
a11 |
a12 |

Row 2: |
a21 |
a22 |

Matrix B

2×2 |
Column 1 |
Column 2 |

Row 1: |
3 |
−5 |

Row 2: |
0 |
4 |

Then a11 = 3, a12 = −5, a21 = 0 and

a22 = 4.

If we have two matrices:

Matrix 1

2×3 |
Column 1 |
Column 2 |
Column 3 |

Row 1: |
5 |
7 |
3 |

Row 2: |
9 |
1/5 |
4 |

Matrix 2

2×3 |
Column 1 |
Column 2 |
Column 3 |

Row 1: |
+√25 |
7 |
3 |

Row 2: |
9 |
0.2 |
4 |

They are equal.
