Horzcat error with num2str in disp function.

When I run the following script:

    A = [5,6,7;8,9,10;11,12,13];
    disp(['The values in A are' num2str(A) '.'])

I get the following error message:

    Error using horzcat
    Dimensions of matrices being concatenated are not consistent.

Why?

Answer 1

Because A is 3x3 whereas the string is 1xlength(). Use

disp(['The values in A are' num2str(A(:).') '.'])

Another option:

A = [5,6,7;8,9,10;11,12,13];
disp('The values in A are ')
disp(A)
