[Octave-bug-tracker] [bug #50102] dlmread crashing the interpreter on Cygwin

[Rik]

Follow-up Comment #17, bug #50102 (project octave):

If no delimiter is found then cmax is not incremented; But this is the correct
behavior for corner cases.  For example, create a text file with a few
newlines and use dlmread on it.  It will return '[]' because the file was
empty.  However if you increment cmax to 1 then it will return a '0' for each
line because it thought there was at least one column of data when there
really wasn't.

With a test file 'abc' of three newlines


octave:1> z = dlmread ('abc')
z = [](32x0)


It is a very minor nit, but it would be better to return a 0x0 empty matrix in
this case.

Secondly, the resize function does accepts a zero as input without problem. 
In the Octave interpreter,


octave:1> x = magic(3)
x =

   8   1   6
   3   5   7
   4   9   2

octave:2> resize (x, 3,0)
ans = [](3x0)
