Multiplication of Matrices
Multiplication of matrices is a fundamental operation in linear algebra, essential for various applications in mathematics, science, and engineering. Unlike addition or subtraction, matrix multiplication is not commutative, meaning the order of multiplication matters. To multiply two matrices, the number of columns in the first matrix must equal the number of rows in the second matrix. The resulting matrix has dimensions equal to the number of rows of the first matrix and the number of columns of the second matrix. Matrix multiplication plays a crucial role in transformations, solving systems of linear equations, and representing complex relationships in data analysis.
