Writing to .mat files

I have created a function like so:

func(a,b,c,d)

and inside the function I will create a variable matrix where the function will fill the matrix like so:

1 b c d
2 b c d
3 b c d
4 b c d

I want to write these values to a .mat file let's say test.mat. However in test.mat, there can be more than one variable matrix. The user will input the first matrix called x and that will be in test.mat. The user can also input a different matrix y and that will also be in test.mat. So basically i want to be able to add different matrices in test.mat without affecting the other matrices in test.mat.

especially the -append keyword. You'll find using the command form of the function call much more amenable to deal with variable names than otherwise.
