The order of rotation operations is from right to left; the matrix adjacent to the column vector is the first to be applied, and then the one to the left. [ 3 ] Conversion from rotation matrix to axis–angle
which can be found by stacking into matrix form a set of equations consisting of the above difference equation and the k – 1 equations =, …, + = +, giving a k-dimensional system of the first order in the stacked variable vector [+] in terms of its once-lagged value, and taking the characteristic equation of this system's matrix.
After the algorithm has converged, the singular value decomposition = is recovered as follows: the matrix is the accumulation of Jacobi rotation matrices, the matrix is given by normalising the columns of the transformed matrix , and the singular values are given as the norms of the columns of the transformed matrix .
Conventionally, i is the row index, numbered from top to bottom, and j is the column index, numbered from left to right. For an m × n matrix, the amount of memory required to store the matrix in this format is proportional to m × n (disregarding the fact that the dimensions of the matrix also need to be stored). In the case of a sparse matrix ...

Several key mistakes could throw off the accuracy of blood pressure readings for people who take them at home. The average "normal" blood pressure is 120/80, according to the American Heart ...
A complex-valued square matrix is normal (meaning , =, where is the conjugate transpose) if and only if it can be decomposed as =, where is a unitary matrix (meaning =) and = diag(, …,) is a diagonal matrix. [7] The columns ,, of form an orthonormal basis and are eigenvectors of with corresponding eigenvalues , …,.
Stock indexes drifted to a mixed finish on Wall Street as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 slipped less than 0.1% ...
