frmtspc1='Hi, my name is %s and my major is %s.\nI started at Cal in %d.';
frmtspc='This entire char array has length %d.\n';
G=sprintf(frmtspc1,name,major,year);

In order to see M, you need to assign the output of myGreeting to two variables, such as
[A, B] = myGreeting('Inigo Montoya', 'sword fighting', 1964);
disp(A)
disp(B)

When you call a function in MATLAB without an output, most of the time MATLAB assigns the first output from that function to a special variable named ans.
Call your function with one or more output arguments and MATLAB will assign the appropriate number of outputs that your function is declared to return into those output arguments. For example, in Guillaume's comment myGreeting is called with two output arguments, A and B. MATLAB will take the first output argument myGreeting says it will return (the variable G) and assign it into the variable named A, and similarly for the variables M and B.
