help with format +

Rik-4
Could someone try the following code under Matlab?

x = ones (3,3);
x(2,2) = 0;
x([1, 3], [3, 1]) = -1;
format +
x
sx = sparse (x)

Thanks,
Rik

r2018a prerelease (copied in one time into terminal so consecutive answers,
but clear enough):

>> format compact
>> x = ones (3,3);
x(2,2) = 0;
x([1, 3], [3, 1]) = -1;
format +
x
sx = sparse (x)
x =
-+-
+ +
-+-
sx =
   (1,1)   -
   (2,1)   +
   (3,1)   -
   (1,2)   +
   (3,2)   +
   (1,3)   -
   (2,3)   +
   (3,3)   -
