%% Random Columns of Matrix % Compute the correlation coefficients for a matrix with two normally % distributed, random columns and one column that is defined in terms of % another. Since the third column of |A| is a multiple of the second, these % two variables are directly correlated, thus the correlation coefficient % in the |(2,3)| and |(3,2)| entries of |R| is |1|. % Copyright 2015 The MathWorks, Inc. x = randn(6,1); y = randn(6,1); A = [x y 2*y+3]; R = corrcoef(A)
