This works in numpy 0.9.7.2416 but doesn't work in numpy 0.9.9.2683:

Numpy 0.9.9.2683 x = asmatrix(zeros((3,2), float)) y = asmatrix(rand(3,1)) y matrix([[ 0.49865026], [ 0.82675808], [ 0.30285247]]) x[:,1] = y > 0.5 x matrix([[ 0., 0.], [ 0., 0.], <--- this should be one (?) [ 0., 0.]])

With r2691 I see

In [7]: x = N.asmatrix(N.zeros((3,2)),float)

In [8]: y = N.asmatrix(N.rand(3,1))

In [12]: x[:,1] = y > 0.5

In [13]: x Out[13]: matrix([[ 0., 1.], [ 0., 1.], [ 0., 1.]])

Cheers Stéfan
