We're current copy by creating an Eigen::Map into the input numpy array, then assigning that to the basic eigen type, effectively having Eigen do the copy. That doesn't work for negative strides, though: Eigen doesn't allow them. This commit makes numpy do the copying instead by allocating the eigen type, then having numpy copy from the input array into a numpy reference into the eigen object's data. This also saves a copy when type conversion is required: numpy can do the conversion on-the-fly as part of the copy. Finally this commit also makes non-reference parameters respect the convert flag, declining the load when called in a noconvert pass with a convertible, but non-array input or an array with the wrong dtype. |
