Remarks

The arguments row0 , row1 , row2 , and row3 are __m128 values whose elements form the corresponding rows of a 4-by-4 matrix. The matrix transposition is returned in arguments row0 , row1 , row2 , and row3 where row0 now holds column 0 of the original matrix, row1 now holds column 1 of the original matrix, and so on.
