Blocked matrix multiply
In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices. Any matrix may be interpreted as a block matrix in one or more ways, with each interpretation defined by how its rows and columns … WebJul 3, 2024 · Matrix multiplication is used in many scientific applications and recently it has been used as a replacement for convolutions in Deep Neural Networks (DNNs) using the im2col operation.
