The Equate(u,v) command receives the rectangular structures u and v, typically of type list, Array, Matrix or Vector, and returns a list of equations, where the left-hand sides of the equations are taken from u and the right-hand sides from the corresponding components of v. The two input objects, u and v, must have the same shapes and sizes, and if only one is an Array then its indices must start at 1.

Equate can also receive two algebraic structures u and v representing vectors of the Vectors subpackage of the Physics package, in which case the list of equations returned is constructed equating the components of u and v. When u and v are projected into different orthonormal basis, the second one is first reprojected onto the basis of the first one; then the components are equated.
