Details:

Here is how to reproduce the behavior:

Take a text file with space delimited numbers in exponential notation.
Something like this (testdata.txt):


2.00E+002 4.00E-004


Then, use the "importdata" command to import those numbers:


filename = 'testdata.txt';
data1 = importdata(filename,' ') % OK
data2 = importdata(filename)     % wrong


The first command (with the explicit space delimiter) works fine. The second
one (without a specified delimiter) produces a wrong result:


data1 =
   2.0000e+02   4.0000e-04
data2 =
   2 + 0i   2 + 4i  -4 + 0i


This happens with the Octave 3.8.2 release both in the Linux and in the
Windows (MXE) version.

In Matlab both versions of the importdata command return the same and correct
result.
