Definition (undergraduate level)
A set of components - each of which is defined as a function of position in some co-ordinate system - which obeys some given transformation law. A tensor of order n has n2 components.
This is a generalisation of the idea of a vector; in fact a vector is a tensor of order 1. A tensor of order zero is a scalar.
A tensor can often be thought of as an array of values and manipulated like a matrix.
