The algorithm first finds a pseudoperipheral vertex of the graph of the matrix. The algorithm will check to see if A is symmetric and use a more efficient algorithm if it is. This is primarly due to the simpler memory stucture of a full matrix which allows for the extended optimization of the matrix-vector algorithms. The multiplication between two 1000*1000 matrixes will take no more than 1 second in matlab. Please am finding it difficult to modify the code to enable the strassen algorithm applicable for odd dimensions. Directed and undirected graphs, adjacency, Graph adjacency matrix. Sparse matrix algorithms lie in the intersection of graph theory and numerical 11 days to 7 minutes when my QR factorization method was added to MATLAB. Det computes the determinant from the triangular factors obtained by Gaussian elimination with the lu function. This is much faster than x=A\b for large matrices. Exiting due to infeasibility: An all-zero row in the constraint matrix does not have a zero in corresponding right-hand-side entry. If A is an M-by-N tall matrix where M > N, A \ B is the same as (A'*A) \ ( A'*B) . This MATLAB function solves the system of linear equations A*x = B. [4] describe and compare many algorithms for computing a matrix exponential. Dftmtx takes the FFT of the identity matrix to generate the transform matrix. Incidence, Graph incidence matrix. The algorithm expm uses is described in [1] and [2].
