Mat Mul Opencv

This operation multiplies matrix a of size a x b with matrix b of size b x c to produce matrix c of size a x c. A b a b a s a s s a s a a scaling. It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat.

Mat mul opencv. This is a list of implemented matrix operations that can be combined in arbitrary complex expressions here a b stand for matrices mat s for a scalar scalar alpha for a real valued scalar double. Here are some examples. N dimensional dense array class. C a b aab bbc cac.

Matrix multiplication is where two matrices are multiplied directly. A alpha per element multiplication and division. Multiplication can be done using opencv s multiply function similar to the mat mul function while division can be performed using the divide function. Public mat mul mat m double scale mul public mat mul mat m ones public static mat ones int rows int cols int type ones public static mat ones size size.

Again both operations can be performed with a matrix and a scalar. The same can be done with the division operation. The class mat represents an n dimensional dense numerical single channel or multi channel array. In opencv it is achieved using the simple operator.
