This very extensive group of functions is provided to deal with matrices.
The scope of functions and abilities covered in this group is in fact vastly
greater than would be required by the average high school student or
teacher. In many cases supplying an explanation in more detail than the
manual of what the function is used for would occupy many pages to no real
useful gain. Consequently many of the functions will be covered only by the
comment “See User’s manual”.
A detailed set of examples for the more commonly used functions is given in
the chapter titled “Using Matrices on the hp 39g+”. See page 170.
COLNORM
See User’s manual
COND
See User’s manual
CROSS([vector],[vector])
This function finds the cross product of two
vectors. Vectors for this function are written as
single row matrices.
For example,
3
(3,4,0) or 4
0
a
=
would be written as [3,4,0].
Note: If you want to use the Matrix Catalog
to define your matrices for use with this
function then you must use the key
to define them as real vectors rather than
as matrices as the CROSS function is
one of the few for which this matters.
