How to Multiply Matrices. A Matrix is an array of numbers: (This one has 2 Rows and 3 Columns) To multiply a matrix by a single number is easy: These are the calculations: We call the number ("2" in this case) a scalar, so this is called "scalar multiplication". Multiplying a Matrix by Another Matrix.
In mathematics, specifically in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix.
In this article, you will learn how to multiply a matrix by another matrix, its algorithm, formula, 2×2 and 3×3 matrix multiplication with examples in detail.
When you multiply a matrix on the left by a vector on the right, the numbers making up the vector are just the scalars to be used in the linear combination of the columns as illustrated above. Here is the formal definition of how to multiply an \(m\times n\) matrix by an \(n\times 1\) column vector.
