If you use a backend that supports row major (e.g., ATLAS), the bindings will have no problem with matrices in row_major format. If you pass a row_major matrix to an implementation that does not support row_major, the bindings automatically tries to pass it as a transposed column_major matrix. In short: whenever possible, row_major is supported by the bindings.
