foo = eye (5); foo(1:3,:)(1:6) = 1

[Etienne Grossmann]

  Hello,


I was surprised to see that 

   foo = eye (5); foo(1:3,:)(1:6) = 1


   error: in indexed assignment of matrix, last lhs index must be ()
   error: assignment failed, or no method for `matrix = scalar'
   error: evaluating assignment expression near line 32, column 32

doesn't work w/ octave-2.1.53. Is that normal, or a bug?

  The only workaround I can think of is :

   foo(reshape(1:prod(size(foo)),size(foo))(1:3,:)(1:6)) = 1

   foo =
 
      1  1  0  0  0
      1  1  0  0  0
      1  1  1  0  0
      0  0  0  1  0
      0  0  0  0  1

  Can anyone give me some insight?

  Cheers,

  Etienne
