reading NaN with fscanf

[Claudio Belotti]

hi all,
        I want to read an ascii file like this:

data_name_1 [data_dimension]
1
2
3
nan
nan
4
5

data_name_2 [data_dimension]
.
.

after reading the string I use fscanf to get the numerical values,

[this_data,count]=fscanf(fh,"%f",[1,this_dimension]);

but as soon as I found "nan" fscanf returns.
I handle this checking count and this_dimension, is there a way to let 
fscanf accept both digit and "nan"?

thanks

Claudio
