How to Multiply Matrices?
Matrices multiplication is a fundamental mathematical operation that is widely employed in domains such as physics, computer science, and engineering. It entails joining rows and columns from two matrices to form a new matrix. However, not all matrices can be multiplied; their size must match certain specifications. This approach, while simple for smaller matrices, becomes into a powerful tool for solving difficult issues in machine learning, graphics, and data analytics.
Matrix multiplication is possible only if –
- The number of columns in the first matrix = the number of rows in the second matrix.
Let the matrices be –
- A: m × n (rows m, columns n)
- B: n × p (rows n, columns p)
The resulting matrix C will have dimensions m × p.
