Details:

octave-3.6.2.exe:2> feval(inline('sum(x(:))'),[1,2;3,4])
error: `x' undefined near line 2 column 9
error: evaluating argument list element number 1
error: called from:
error:    at line -1, column -1

If you change x(:) to x, feval will work. There is workaround to reshape
matrix x to an array (like reshape(x,prod(size(x)),1)  ), but in case you need
to get something by index, it will not work.
