Continuous cross product formula
The formula of cross multiplication is a×(b×c)=b(ac)? C(ab), cross product, also called outer product and cross product in mathematics, and vector product and cross product in physics, is a binary operation of vector in vector space, and its operation result is a vector instead of a scalar.

In mathematics, vectors (also known as Euclidean vectors, geometric vectors and vectors) refer to quantities with magnitude and direction.

The most important method of matrix multiplication is generalized matrix product. It only makes sense when the number of columns in the first matrix is the same as the number of rows in the second matrix.

When we generally refer to matrix product, we mean general matrix product. The matrix of m×n is a digital array in which m×n numbers are arranged in m rows and n columns. Because it compactly concentrates a large amount of data together, sometimes it can simply represent some complex models, such as power system network model.
