Aux. functions with multiple outputs

[Mike B.]

Hi All,

Is it possible to define an aux. function which handles multiple outputs?.

For example, for a single output:
function [ a ] = f1( x )
...
endfunction
y = @(x) f1( x );  # aux. function, single output
sin( y )

However if f1 returns multiple outputs:
function [ a,b ] = f1( x )
...
endfunction

how do I define y so I can refer to a and b?.

Thanks,
Mike.
