Additionally we use in Germany the "," as decimal point. So I have to convert the imported file-contents: In[1]:= zufall = Import["temp.csv", "CSV", ConversionOptions -> {"NumberPoint" -> ","}]; and now I can use the 8x8 array as usual: In[2]:= Plus @@ Flatten @ zufall] / Times @@ Dimensions @ zufall Out[2]= 0.49825710699789416 Hope, this hint helps, Peter -- Peter Pein, Berlin GnuPG Key ID: 0xA34C5A82 http://people.freenet.de/Peter_Berlin/
