Dear Community

I am currently working on writing a wrapping from Matlab to Simulink. In Matlab (2020a) we create sparse matrices and we would like to use them in Simulink. Despite extensive research I haven't found a way to pass them into Simulink without converting them into full matrices (which then leads to a memory overflow for the real use case). I looked also into statements that passing sparse matrices is not possible but haven't found anything meaningful.

I feel that there should be a way since Matlab and Simulink themself can both work with sparse matrices. Any hint pointing out if and how it is possible or why it isn't possible is highly appreciated.

Thank you in advance for your help

Best regards
