Add output of a function to a struct without deleting the previous struct

Hello, i want to call a function twice with different input and store both outputs inside the same struct. The output of the first call shall not be replaced, i need both outputs inside the struct.

Function:

function [Test1] = Test(A)
if A==2
    B=A*2;
    Test1.B1=B;
else
    B=A*3;
    Test1.B2=B;
end
end

Skript:

[Test1]=Test(2);
[Test1]=Test(3);

Like this, the second part ([Test1]=Test(3)) replaces the output of the first part.

I will greatly appreciate any assistance.

I just found the solution:

The struct has to be called in Output & Input!

Function:

function [Test1] = Test(Test1,A)
if A==2
    B=A*2;
    Test1.B1=B;
else
    B=A*3;
    Test1.B2=B;
end
end

Skript:

[Test1]=Test(Test1,2);
[Test1]=Test(Test1,3);
