Hi i want to display two strings in one function but G is showing but M is not i dont know what the problem is kindly help me??

function [G,M]=myGreeting(name, major, year)

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);

D=size(G,2);

M=sprintf(frmtspc,D);

end

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)

[Arslan Ahmad]

I am using sprintf

[Arslan Ahmad]

my output is like this by using disp

myGreetings('ars','fds',4321)

Hi, my name is ars and my major is fds.

I started at Cal in 4321.

This entire char array has length 65.

ans =

Hi, my name is ars and my major is fds.

I started at Cal in 4321.

If you don't specifically ask for inputs matlab only returns the first one. So as Walter said, if you want to see the two outputs, you have to ask for two outputs by giving two output variables when you call the function:

>>[A, B] = myGreeting('Inigo Montoya', 'sword fighting', 1964)
A = 
  Hi, my name is Inigo Montoya and my major is sword fighting
  I started at Cal in 1964.

B = 
  This entire char array has length 49.

yeah i tried that too but it is showing after two strings

ans=

and shows again first string how do i suppress ans please help

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.
