2. Matrix multiplication algorithm - Wikipedia

   en.wikipedia.org/wiki/Matrix_multiplication...

   The definition of matrix multiplication is that if C = AB for an n × m matrix A and an m × p matrix B, then C is an n × p matrix with entries = =. From this, a simple algorithm can be constructed which loops over the indices i from 1 through n and j from 1 through p, computing the above using a nested loop:

3. Strassen algorithm - Wikipedia

   en.wikipedia.org/wiki/Strassen_algorithm

   The left column visualizes the calculations necessary to determine the result of a 2x2 matrix multiplication. Naïve matrix multiplication requires one multiplication for each "1" of the left column. Each of the other columns (M1-M7) represents a single one of the 7 multiplications in the Strassen algorithm. The sum of the columns M1-M7 gives ...

4. Matrix multiplication - Wikipedia

   en.wikipedia.org/wiki/Matrix_multiplication

   Matrix multiplication shares some properties with usual multiplication. However, matrix multiplication is not defined if the number of columns of the first factor differs from the number of rows of the second factor, and it is non-commutative, [10] even when the product remains defined after changing the order of the factors. [11] [12]

5. Computational complexity of matrix multiplication - Wikipedia

   en.wikipedia.org/wiki/Computational_complexity...

   In theoretical computer science, the computational complexity of matrix multiplication dictates how quickly the operation of matrix multiplication can be performed. Matrix multiplication algorithms are a central subroutine in theoretical and numerical algorithms for numerical linear algebra and optimization, so finding the fastest algorithm for matrix multiplication is of major practical ...

6. Square root of a 2 by 2 matrix - Wikipedia

   en.wikipedia.org/wiki/Square_root_of_a_2_by_2_matrix

   A square root of a 2×2 matrix M is another 2×2 matrix R such that M = R 2, where R 2 stands for the matrix product of R with itself. In general, there can be zero, two, four, or even an infinitude of square-root matrices. In many cases, such a matrix R can be obtained by an explicit formula.

7. Conformable matrix - Wikipedia

   en.wikipedia.org/wiki/Conformable_matrix

   Multiplication of two matrices is defined if and only if the number of columns of the left matrix is the same as the number of rows of the right matrix. That is, if A is an m × n matrix and B is an s × p matrix, then n needs to be equal to s for the matrix product AB to be defined.

9. Conjugate transpose - Wikipedia

   en.wikipedia.org/wiki/Conjugate_transpose

   That is, denoting each complex number by the real matrix of the linear transformation on the Argand diagram (viewed as the real vector space ), affected by complex -multiplication on . Thus, an m × n {\displaystyle m\times n} matrix of complex numbers could be well represented by a 2 m × 2 n {\displaystyle 2m\times 2n} matrix of real numbers.
