MATLAB: I have different answer using ‘norm’. Do I miss something norm A = [1 2; 3 4]; norm(A) >> 5.4650 But equivalently, sqrt(1^2 + 2^2 + 3^2 + 4^2) >> 5.4772 the answer is different Do I miss something? thx! Best Answer norm(A) and norm(A,'fro') are different things.Best wishesTorsten. Related SolutionsMATLAB: Norm of A = [2 3; 1 -1] not equal to sqrt(15) norm(A)=sqrt(maximum eigenvalue of A'*A)You want norm(A,'fro'), I guess.Best wishesTorsten. MATLAB: X.coords = something This creates a field in the structure y. This field is a cell array. Look at this:Y.myfield = 2;Y.yourfield = 3;Y % Show the structure Y.Y.ourfield{1} = magic(3);Y.ourfield{2} = magic(4);Y % Show the structure Y.Now to access the values stored in the fields of the structure Y, use structure addressing:R = Y.myfieldS = Y.yourfieldT = Y.ourfield{2}For more information, search the documentation for structures.
