WebMar 24, 2024 · The inner product of two vectors (Image by author) Dot product. The dot product is defined for matrices. It is the sum of the products of the corresponding elements in the two matrices. To get the dot product, the number of columns in the first matrix should be equal to the number of rows in the second matrix. There are two ways … WebSpecifically, the sign of an element in row i and column j is (-1)^ (i+j). Sum up all the products obtained in step 3 to get the determinant of the original matrix. This process may look daunting for larger matrices, but it can be simplified by choosing a row or column that has many zeros or that has a repeated pattern.
