Web5 de abr. de 2024 · Matrix storage in memory as a multidimensional array. In mathematics, a matrix is defined as a rectangular array of numbers arranged in rows and columns. For example, the matrix below has 3 rows and 5 columns, and can be referred to as a \mathbf {3 \times 5} 3×5 matrix. WebD = pageeig (X) returns the eigenvalues of each page of a multidimensional array. Each page of the output D (:,:,i) is a column vector containing the eigenvalues of X (:,:,i). Each page of X must be a square matrix. [V,D] = pageeig (X) computes the eigenvalue decomposition of each page of a multidimensional array. options in google sheets
