The simplest way to define a vector is as a list of its elements.
Maple easily performs addition and multiplication of vectors and matrices.
For example, to be added, two matrices must be of the same dimensions. To see the output of a calculation displayed as a vector, use the command evalm . If an eigenvalue occurs with multiplicity greater than one, it will be repeated in the list. If necessary, eigenvalues are expressed as complex numbers. June 4th, 1996.
