I am trying to read a file with 80 columns having 5 floats of 16 columns each. Because of the format sometimes there is no delimiter. For example I am trying to read the line

-4.789814200D+02 3.243617760D+01 3.128760036D+00 1.178067806D-02-8.318441350D-05

which has no delimiter between floats 4 and 5.

textscan(fid,'%f %f %f %f %f',1) is giving me NaN on the last number
textscan(fid,'%16f %16f %16f %16f %16f',1) is also giving me a Nan on the last number

cannot use %N.df due to the data being in exponential format.

I am stumped. Any help is greatly appreciated.

Which version are you using? In 2008b I get,

>> S = '-4.789814200D+02 3.243617760D+01 3.128760036D+00
1.178067806D-02-8.318441350D-05';
>> textscan(S,'%16f %16f %16f %16f %16f',1)
ans =
[-478.98142] [32.4361776] [3.128760036] [0.01178067806]
[-8.31844135e-05]

Thanks for the reply. I am running Matlab 7.1. I will upgrade tonight and see if it works.
