The problem is that some object in your workspace requires a package 
that you don't have installed.  From the message, it looks like SparseM 
is needed: do you have that?  If it's not that, it's probably some other 
package that exports a kronecker method, but I can't tell you what.

If you can identify exactly what solves this, and it isn't just 
installing SparseM, then please post details.
