MatN = Mat./max(abs(Mat))

where Mat is the matrix you want to normalize.

This script normalizes the complex matrix A by dividing it by its Frobenius norm

% Suppose A is your complex matrix

A = [1+2i, 2-1i; -1+1i, 1-1i];

% Calculate the norm of the matrix

normA = norm(A, 'fro'); % Frobenius norm

% Normalize the matrix

A_normalized = A / normA;

disp(A_normalized);
