Details:

It's not really a bug, just a difference between sparse and full matrices. I
guess sparse should be tolerant of this kind of abuse, just like it's full
sibling :)


>> A=zeros(4,4);
>> A(:,1) = 1:4
A =

   1   0   0   0
   2   0   0   0
   3   0   0   0
   4   0   0   0

>> A=sparse(4,4);
>> A(:,1) = 1:4
error: A(I,J,...) = X: dimensions mismatch
>> A(:,1) = (1:4)'
A =

Compressed Column Sparse (rows = 4, cols = 4, nnz = 4 [25%])

  (1, 1) ->  1
  (2, 1) ->  2
  (3, 1) ->  3
  (4, 1) ->  4

>> full(A)
ans =

   1   0   0   0
   2   0   0   0
   3   0   0   0
   4   0   0   0
