-- Row and Column-wise scaled: All of the rowwise elements in A Matrix and columwise elements in B Matrix will share the same quantization element and the elementwisde operation will complete in epilogue.
+- Row and Column-wise scaled: All of the row-wise elements in A Matrix and column-wise elements in B Matrix will share the same quantization element and the element-wise operation will complete in epilogue.
 - Tensor-wise scaled: Share the same scalar scale across the whole tensor of A or B
