In this paper we present unified parallel algorithms for Gaussian elimination, with partial and complete pivoting, on product networks. A parallel algorithm for backward substitution is also presented. The proposed algorithms are network independent and are also independent of the matrix distribution ...
We have . However, , so we interchange the second row with the third:The only entry below is already zero, so we do not need to perform row additions. We are done with the penultimate row, so the Gaussian elimination algorithm stops. The matrix of coefficients (to the left of the ...
When a system is reduced in this way, I can just read off the values of x, y, and z directly from the system; I don't have to bother with the back-substitution. This more-complete method of solving is called "Gauss-Jordan elimination" (the "Jordan" part being named after Wilhelm ...
the m th step of which consists of subtracting a multiple of the m th equation from each of the following ones so as to eliminate one variable, resulting in a triangular set of equations which can be solved by back substitution, computing the n th variable from the n th equation, the ...
We now formally describe the Gaussian elimination procedure. Start with matrix A and produce matrix B in upper-triangular form which is row-equivalent to A. If A is the augmented matrix of a system of linear equations, then applying back substitution to B determines the solution to the system...
ReducedRowEchelonForm can use either Gaussian Elimination or the Bareiss algorithm to reduce the system to triangular form. If the Bareiss algorithm is used, the leading entries of each row are normalized to one and back substitution is performed, which avoids normalizing entries which are eliminated...
