Hi Ahmet,
You can execute the following command (as mentioned under Limitations section for the "symmatrix" funciton) to find the functions which currently accept symbolic matrix variables as input
methods symmatrix
solve currently does not support symbolic matrix inputs (as also mentioned by @Walter Roberson)
Hope this helps
