Function MainProcess Error on Ubuntu

Hi, I'm fairly new at Matlab. I managed to successfully run it on Ubuntu (MacBookPro Partition) and now I am trying to run this main process:

function []= MainProcess(defaultPara, Fdir)

When I run it, it gives me this error:

Error in MainProcess (line 54)
ops = sdpsettings('solver','sedumi','verbose',1);

I checked solver, sedumi and verbose values and I need help.
