Sparse Matrix Multiplication

Is there any specific method to multiply sparse matrices in Compose?

I've tried to use the array '.*' and the matrix '*' operator and in both cases the same message appears 'Error: unsuported  operation...'.

    Sparse*sparse multiplication is not yet supported but will be in v2020 (using both operators).

    Hello Rodolfo,

     

    Can you tell us how big and 'sparse' are your matrices? And what is your application?

     

    Thanks,

    I need to execute the multiplication of 3 sparse matrices (12x12 each). Two of them has 36 non zero elements and the other one has 40 non zero elements.
