It sounds like you just need to add a reference to Spreadsheet link EX in your VBA code. Select tools -> references and then tick the spreadsheet link EX library. After that it should work.

Alternately you can call addin functions without adding references using application.run. So try application.run "matlabinit". But I think in this case adding a reference is preferable as you are unlikely to be distributing a spreadsheet calling matlab.

Also have you made sure the addin is installed? In excel 2010 click on the developer tab, choose addins (with the big gold gear icon) and tick the Spreadsheet Link Ex Ver… for use with Matlab. Then go into VBA and add the reference as described above.
