The CKM matrix, VV, relates the quark mass and flavor bases. In the standard model, VV is unitary 3×3, and specified by four arbitrary parameters, including a phase allowing for CPCP violation. We review the experimental determination of VV, including the four parameters in the standard model context. This is an active field; the precision of experimental measurements and theoretical inputs continues to improve. The consistency of the determination with the standard model unitarity is investigated. While there remain some issues the overall agreement with standard model unitarity is good.
