multiple outputs from a function

Dear All,
I am facing a problem with delivering multiple outputs from a function. Take an example, function [a b c]= g()% no input a=1 b=2 c=3 end
However, this function will only deliver the value for a as the 'ans' and ignore value of b and c. I think I have made it clear that this function should deliver value for a, b and c. and they can be used for corresponding calculations in another function.
Could somebody help me with it?
Thank you very much in advance.

Show what syntax you are using to call the function when it only gives you the first output argument.

And what syntax are you using for the function g itself?

If you are simply calling g() at the command line with no output arguments
>>g()
then MATLAB assumes that you only want 1 output argument and will assign that to ans.
If you want 2 or more output arguments, you must make that explicit, e.g.,
>>[a,b]=g()
or
>>[a,b,c]=g()
