  Monografia 1: Para el curso Análisis y Diseño de Algoritmos
Strassen's algorithm has long suffered from the erroneous assumptions that it is not efficient for matrix sizes that are seen in practice and that it is unstable.
Originally, Strassen suggested padding the input matrices with extra rows and columns of zeros, so that the dimensions of all the matrices encountered during the recursive calls are even.
Strassen's algorithm as stated in Section 2 <#secreview> uses four temporary variables in stage (1), four temporary variables in stage (2), seven temporary variables in stage (3), and seven temporary variables in stage (4).

 Examples of use   (Site not responding. Last check: )
Strassen's matrix multiplication algorithm is able to perform this calculation in time
Thus one might be able to speed up the code by using Strassen's algorithm instead of the traditional algorithm.
If one suspects that this is the case one can use comparative debugging to determine if and when the result of Strassen's algorithm differs significantly from that of the ordinary algorithm.

Within the ranking of Europe's largest cities ordered by their number of companies Strassen is on position 1659.(Six months ago it was position 1659)
If we rank all cities by the total sales of all their big companies, Strassen is on position 799.

  Tuning Strassen's Matrix Multiplication for Memory Efficiency
Strassen's algorithm for matrix multiplication gains its lower arithmetic complexity at the expense of reduced locality of reference, which makes it challenging to implement the algorithm efficiently on a modern machine with a hierarchical memory system.
All implementations of Strassen's algorithm that we have encountered use an empirically chosen cutoff criterion for determining the matrix size T at which to terminate recursion.
Furthermore, since Strassen's algorithm is based on divide-and-conquer, an implementation must handle odd-size matrices, and reduce recursion overhead by terminating the recursion before it reaches individual matrix elements.

 Volker Strassen - Wikipedia, the free encyclopedia
In 1971 Strassen published a paper together with Arnold Schönhage on asymptotically-fast integer multiplication; see the Schönhage-Strassen algorithm.
He is also noted for developing, in 1969, an algorithm for asymptotically-fast matrix multiplication, now known as Strassen's algorithm.
In 1999 he was awarded the Cantor medal.

 Intro to Algorithms: CHAPTER 31: MATRIX OPERATIONS
Strassen's algorithm for matrix multiplication, in fact, depends critically on the existence of additive inverses.
Indeed, Strassen's original paper was motivated by the problem of showing that a set of a linear equations could be solved more quickly than by the usual method.
Fischer and Meyer [67] adapted Strassen's algorithm to boolean matrices (Theorem 31.10).

 Matrix Multiplication
Strassen's algorithm is difficult to implement efficiently because of the data structures required to maintain the array partitions.
    That said, an implementation of Strassen's algorithm in Mathematica by Stan Wagon is offered ``without promise of efficiency'' on the algorithm repository WWW site.
Progressive improvements to Strassen's algorithm have gotten progressively less practical.

 strassen matrix multiplication algorithm
By functioning properly is meant that the Classical and Strassen results were subtracted from the Maple Default algorithm results.
Already we notice that the Strassen implementation, while it does function properly for nonsquare matrices of differing sizes, needs to be refined to compete properly with the other two algorithms.
It is immediately apparent that the Strassen implementation does not meet the objective.

 Strassen's Method for Matrix-Multiplication   (Site not responding. Last check: )
C22 in Step 2 achieves the goal of obtaining the product matrix C via Strassen's Method, but this recursive method incurs one less matrix multiplication in each recursion than the original one suggested.
Assuming we have all eight N'xN' block-matrices available, we proceed thusly, with the prototype for recursive function Strassen() defined as: void Strassen(Matrix_t, Matrix_t, Matrix_t, int); input input output input and originally invoked as: Strassen(A, B, C, N).
Then, the seven recursive calls to Strassen() are executed for product-matrices M1...
