To display some text and a matrix, you can use two disp statements. This makes the code easy to understand and maintain.
For example, this code:
A = magic(3)
disp('The result is:')
disp(A)
Displays:
The result is:
8 1 6
3 5 7
4 9 2
If a one line solution is needed, you can use the num2str function to convert the matrix to a character array. This displays the contents of the array as a row vector though, changing the original shape of the matrix. To maintain the original shape of the matrix, use the first approach.
For example, this code:
A = magic(3)
disp(['The result is: [' num2str(A(:).') ']']) ;
Displays:
The result is: [8 3 4 1 5 9 6 7 2]
