WebMar 10, 2008 · Table 6 shows a matrix that was derived from the change detection results obtained from the object-based method. The matrix details the land cover conversions from one land cover type to another between 1999 and 2004. In the matrix, the value in each of the cells was the amount of land that was converted from one land cover type to another. WebLet R and P be the numbers of design responses and design parameters, respectively. Let each response , , be a function of design parameters , and depend on them both explicitly and via the displacement field represented here by the nodal displacement vector (see the definition of finite element interpolation in “ Procedures: overview and basic equations, ” …
WebK r is not a differencing matrix, but by multiplying K r by ( - l) z and adding z columns of appropriate numbers to each side of it, we can extend K r to /~, a differencing matrix of order z. The product K/(" is a differencing matrix of order 2 z. Now extend d by adding z zeros to both ends.
