Matrices are rectangular arrays of numbers, symbols, or expressions, arranged in rows and columns. They are a fundamental concept in mathematics, particularly in linear algebra. A matrix can be denoted with uppercase letters (e.g., \\( A \\), \\( B \\), \\( C \\)), while individual elements within the matrix are often denoted with lowercase letters, often with two indices indicating their position.
