Structure as output of MATLAB Function Block through Simulink.Bus object -

i have matlab function block compute x variables want use later in script.

my first option use to workspace blocks each of them, since have x variables, fills model blocks. problem these x variables have different dimensions, otherwise build matrix.

my idea build structure within matlab function block , use single to workspace block, research told me need simulink.bus object so.

is approach @ best way achieve goal? in advance input!
