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.
