Note that norm(A), where A is an n-element vector, is the length of A. Remarks To obtain the root-mean-square (RMS) value, use norm(A)/sqrt(n). Returns sum(abs(A).^ p )^(1/ p ), for any. When A is a vector, slightly different rules apply: The Frobenius-norm of matrix A, sqrt(sum(diag(A'* A))). T he infinity norm, or largest row sum of A, max(sum(abs(A'))). The largest singular value (s ame as norm(A)). The 1-norm, or largest column sum of A, max(sum(abs((A))). Returns a different kind of norm, depending on the value of p: Returns t he largest singular value of A, max(svd(A)). The norm function calculates several different types of matrix norms: n = norm(A) If x is a matrix the 2 norm will be computed as follow: n21 x 21 sumj ( sumi x(i,j)2 )(1/2) In this case, all other argument are. Norm (MATLAB Function Reference) MATLAB Function ReferenceÄescription The norm of a matrix is a scalar that gives some measure of the magnitude of the elements of the matrix.
