Matrix multiplication wolfram

The Wolfram Language's matrix operations handle both numeric and symbolic matrices, automatically accessing large numbers of highly efficient algorithms. The Wolfram Language uses state-of-the-art algorithms to work with both dense and sparse matrices, and incorporates a number of powerful original algorithms, especially for high-precision and symbolic matrices.

Matrix multiplication wolfram. Strassen in this case does not itself make the algorithm asymptotically faster, but since the bulk of cost is in large integer multiplications one gets a 1/8 speed boost on those parts of the algorithms that use 2x2 matrix products. If memory serves me correctly this gives an overall gain factor somewhere close to 1/8 (maybe 10% or so). Share.

Scalar multiplication Given a vector a and a real number (scalar) λ, we can form the vector λa as follows. If λ is positive, then λa is the vector whose direction is the same as the direction of a and whose length is λ times the length of a. In this case, multiplication by λ simply stretches (if λ>1) or compresses (if 0<λ<1) the vector a.
