Fprintf not showing up in function output

Hello, I made a function that calculates the area or volume of a matrix that is linear. And, I got the math stuff down but I am not sure how to display the text so it can output a complete sentence. Here is function code:

It shows the corresponding sentence for (A) but for (B) it shows just the value of D.

function(D) = areavol(A)
R = rank(A); 
[rows,col] = size(A);
D = abs(det(A));
if col == 3 
    word = 'parallelepiped';
else 
    word = 'parallelogram';
if rows > R
    D = 0;
    fprintf('Error,%s is not linearly independent and the area or volume is %g',word,D);
else 
     if col == 3 
        fprintf('The volume of the parallelepiped is %g cubic units',D)
    else 
        fprintf('The area of the parallegram is %g square units',D)
    end 
    
end 
end
% (A) 
A = randi(10,2)
%(B)
A = fix(10*rand(3))

Hi Gurinder,

When we assign "A = fix(10*rand(3))", the variable "A" stores a matrix of 3X3. In the code you have provided (I have attached the code with adjusted indentation below), when the number of columns is 3 you are only assigning to variable "word" and not printing anything. Therefore you do not see any print statement.

function D = areavol(A)
R = rank(A);
[rows,col] = size(A);
D = abs(det(A));
if col == 3
    word = 'parallelepiped';
else
    word = 'parallelogram';
    if rows > R
        D = 0;
        fprintf('Error,%s is not linearly independent and the area or volume is %g',word,D);
    else
        if col == 3
            fprintf('The volume of the parallelepiped is %g cubic units',D)
        else
            fprintf('The area of the parallegram is %g square units',D)
        end
        
    end
end

I assume that you missed adding an "end" in your code after the first else statement.

Hope this helps!
