Problems running Dynare in Octave

Hi,

I am just starting to use Dynare in Octave and I have a problem that I hope somebody can help me with.

After the command “dynare xxx.mod” I receive the following error

"invalid call to str2num. Correct usage is:

–Function File: str2num (S)

does anybody know what it means?

Thank you

Nicola

Solved, thanks
