| * @note The block's dimensions used for reshaping the LHS matrix and the RHS matrix (M0, N0 and K0) must be passed at compile time using -DM0, -DN0 and -DK0 (i.e. -DM0=4, -DN0=8, -DK0=4). |
| * @note The number of M0xK0 vertical blocks stored on the same output row of the reshaped LHS matrix must be passed at compile time using -DV0 (i.e. -DV0=2) |

| * -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D |
| * -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor. |

| * -# Add bias to final result if bias tensor is not a nullptr |
