Hello Tilman,

Is dcc a function you developed? The error message is about calling normlike, mostlikely inside function dcc. Two things you can do:

from matlab command line, type help normlike. This will show you what normlike expects for inputs. Pay attention to the explanation of the first parameter. It is the one giving you error.
Put a breakpoint on the line that calls normlike. See if the first parameter is an array of two elements.

Thanks,

Yongjian
