Matrix A is a tridiagonal matrix; that is, all nonzero elements of A lie on the
main diagonal and the first diagonals above and below the
main diagonal.
The shear deformation of the joints was measured by two displacement sensors placed in the
main diagonal directions, as shown in Figure 3(b).

Where UA and VA are orthogonal square matrices and [summation]A contains singular values on its
main diagonal. The singular value matrix represents the intensity information of the input image and the change on the singular values change the intensity [3].
The last definition we need, about (k, n)-diagrams, is the
main diagonal. As we can see in the Figure 2, it is the line going through the North-West and the South-East corners of the top left cell.
All the diagonals above this
main diagonal (beginning at 10) follow the same suit as the
main diagonal, however all the diagonals below the
main diagonal have the anomaly that the number of elements in these diagonal differs from the beginning number.
In paper [5] other factors that influence the performances of parallel solving equations systems with iterative methods were experimentally identified: a distribution of non-zero elements along and around the
main diagonal of the associated matrix, the ratio between the number of nonzero elements inside and outside of Jacobian submatrix for each partition in part and of course the number of partitions.
The bike is described as having the words 'Mountain Ridge' in white on the
main diagonal frame, has chrome coloured handle bars, a black seat, a black coloured bell and two black hand grips.
