Using variable-size data with Unbuffer Block ?

Hi,
I need to send from a "MATLAB Block" a variable size matrix to an Unbuffer Block. The problem is that is seems that the Unbuffer doesn't accept variable-size signals, as I got this error :
MATLAB Function Interface Error: Simulink cannot propagate the variable-size mode from the output port 1 of 'example/MATLAB Function1' to the input port 1 of 'example/Unbuffer1'. This input port expects a fixed-size mode. The variable-size mode originates from 'example/MATLAB Function1/ SFunction '. Examine the configurations of 'example/Unbuffer1' for one of the following scenarios: 1) the block does not support variable-size signals; 2) the block supports variable-size signals but needs to be configured for them.
The scenario I have is number 1) I guess. What can I do to work around the issue ?
By the way, I use the Unbuffer to transform a matrix into rows (vectors) before being received one-by-one by an HDL cosimulation Block at speific clock rate (it works fine for fixed-size matrix).
Thanks,
regards.

I forwarded your question to our HDLVerifier team. Thanks

Hi, thanks Mr Kintali, It seems to me that it's more a Simulink issue, but it's okay to see HDLVerifier. In which section of the forum I would find answer then ?
Regards.
