Vectors and Matrices
The HP-28S deals with two types of arrays: vectors, which are one-
dimensional arrays, and matrices, which are two-dimensional arrays.
You can enter vectors and matrices as individual objects, called array
objects, and calculate with them as easily as with numbers.
This chapter shows basic array calculations using real arrays-vectors
and matrices whose elements are real numbers. You can also calculate
with arrays whose elements are complex numbers.
All commands in the ARRAY menu are described briefly in appendix
D, uMenu Map." For complete descriptions, refer to U ARRAyn in the
Reference Manual.
Vectors
This section demonstrates vector arithmetic, the cross product, and
the dot product.
