A '''tensor''' in mathematics is a generalisation of vectors and matrices, where the number of indices can be any natural number (as opposed to 1 for vectors and 2 for matrices). The name comes from ''tension'', since the need for these first arose in the study of complex tensions, but they are probably most prominently seen in differential geometry.

'''Tensor''' is also the name of a package by Neil McKay.
