Definition: for an ordered set of n vectors in an n-dimensional space with a given base, scalar attributed to this set by the unique multilinear form taking the value 0 when the vectors are linearly dependent and the value 1 for the base vectors

Note 1 to entry: When the coordinates of the n vectors U1,U2,,Un are arranged as columns or rows of an n×n matrix, the determinant of the vectors is equal to the determinant of the matrix:

det(U1,U2,,Un)=|U11U12U1nU21U22U2nUn1Un2Unn|

Note 2 to entry: According to the sign of the determinant, the set of vectors and the given base have the same orientation or opposite orientations.

Note 3 to entry: For the three-dimensional Euclidean space, the determinant of three vectors is the scalar triple product of the vectors.
