Shortly after the courts created larceny by trick, they created the crime of obtaining property by False Pretenses. Before, a defendant who induced a person to part with the title to property could escape prosecution because the victim transferred not actual possession of the property but only title to the property.
Translation matrix. A translation matrix was a data construct that facilitated the conversion of symbols and sounds from one language to another. It was a major component of communication systems and devices such as the universal translator. Translation matrices were included in the Friendship 1 probe, launched in 2067.
A square matrix A is a normal matrix if [A,A^(H)]=AA^(H)-A^(H)A=0, where [a,b] is the commutator and A^(H) denotes the conjugate transpose. For example, the matrix [i 0; 0 3-5i] is a normal matrix, but is not a Hermitian matrix. A matrix m can be tested to see if it is normal using Wolfram Language function: NormalMatrixQ[a_List?MatrixQ] := Module[ {b = Conjugate @ Transpose @ a}, a. b === b. a ]Normal matrices arise, for example, from a normal equation.
