+Subject: [PATCH] Fix vectorized reductions for Eigen::half
+
+Fixes compiler errors in expressions that look like
+
+ Eigen::Matrix<Eigen::half, 3, 1>::Random().maxCoeff()
+
+The error comes from the code that creates the initial value for
+vectorized reductions. The fix is to specify the scalar type of the
+reduction's initial value.
+
+The cahnge is necessary for Eigen::half because unlike other types,
+Eigen::half scalars cannot be implicitly created from integers.
