Details:

Hello,

I have encountered a problem with the sortrows function, in that it doesn't
seem to be able to deal with arrays with only one row.  

To reproduce my problem, try the following:


sortrows([1], 1)


or:


sortrows([1,2,3,4], 1)


On my machine, the return is a 0xn matrix, where n is the number of columns in
the input matrix.  So, the row has disappeared, whereas I would have expected
it to return the row unaltered.

Running sortrows on matrices with two or more rows seems to work as expected.

This isn't a big issue for me as it is easy enough to wrap calls to sortrows
in an "if" statement, but I thought it might cause compatibility issues and/or
confusion.

I'm using a pre-compiled Arch Linux GNU Octave package on a 32 bit Intel
computer.
