Steps of Strassen’s matrix multiplication: Divide the matrices A and B into smaller submatrices of the size n/2xn/2. Using the formula of scalar additions and subtractions compute smaller matrices of size n/2. Recursively compute the seven matrix products Pi=AiBi for i=1,2,…7. Now comp...
GramianWe design a new parallel algorithm for matrix multiplication by Gramian of Toeplitz-block matrix. This type of computation represents the computationally most intensive task in the iterative methods for the singular value decomposition of data matrices which arise, for example, in the forward-...
COSMA is a parallel, high-performance, GPU-accelerated, matrix-matrix multiplication algorithm that is communication-optimal for all combinations of matrix dimensions, number of processors and memory sizes, without the need for any parameter tuning. The key idea behind COSMA is to first derive a ti...

We design two nondeterministic algorithms for matrix multiplication. Both algorithms are based on derandomization of Freivalds’ algorithm for verification of matrix products. The first algorithm works with real numbers and its time complexity on Real RA
15.2 -Matrix-chain multiplication - same as 15.1, though I don't particularly like the way this section is written (it's rare for me to say that about CLRS). 15.3 -Elements of DP - worth a read so that you understand DP properly, but I'd say it's less important than knowing what...
Inverse transpose of CTM ITCTM = (CTMT)⁻¹ Inverse transpose of CTM2 (required if lighting) ITCTM2 = (CTM2T)⁻¹ In some cases it may be more efficient to blend the matrices first using the vertex's weights, and then do only one (matrix)X(vertex) multiplication.反馈...
Advantages of Divide and Conquer Algorithm The complexity for the multiplication of two matrices using the naive method isO(n3), whereas using the divide and conquer approach (i.e. Strassen's matrix multiplication) isO(n2.8074). This approach also simplifies other problems, such as the Tower of...
