'abs'— Sort rows ofAbyabs(A)whenAis real or complex. If a column ofAhas elements with equal magnitude, then useangle(A)in the interval (-π,π] to break ties. Output Arguments collapse all Sorted array, returned as a column vector or matrix.Bis the same size asA. ...
iscolumn(x)、isrow(x) 判断是否为列向量、行向量 isvector()、ismatrix() 判断是否为向量、矩阵 isempty(x)、isscalar() 判断是否为空向量、单个数值 A = [1]; U = repmat(A, 2, 3); % 结果 U = [1 1 1 1 1 1] repmat(A, 1, 2) % [1, 1] repmat(A, 2, 1) % [1; 1] ...
C=A*Bis the matrix product ofAandB. IfAis an m-by-p andBis a p-by-n matrix, thenCis an m-by-n matrix defined by C(i,j)=p∑k=1A(i,k)B(k,j). This definition says thatC(i,j)is the inner product of theith row ofAwith thejth column ofB. You can write this definition...
which means magic. Used in Matlab to generate magic squares of order n. For example, the third-order magic square is nine numbers from 1 to 9, forming a 3*3 matrix, so that the sum of the three numbers in the three directions of the matrix is always the same regardless of the horiz...
Ifp = 1, thennis themaximum absolute column sumof the matrix. Ifp = 2, thennis approximatelymax(svd(X)). This value is equivalent tonorm(X). Ifp = Inf, thennis themaximum absolute row sumof the matrix. n= norm(X,"fro")returns theFrobenius normof matrix or arrayX. ...
