You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: norm.m
    path of file: ./repos/scGEAToolbox/tensor_toolbox/@ktensor
    
    the code of the file until where you have to start completion: function nrm = norm(A)
%NORM Frobenius norm of a ktensor.
%
%   NORM(T) returns the Frobenius norm of a ktensor.
%
%   See also KTENSOR.

% Compute the matrix of correlation coefficients
coefMatrix = A.lambda * A.lambda';
for i = 1:ndims(A)
    coefMatrix = coefMatrix .* (U{i}' * U{i});
