Here is a program that uses the
Matrix
class to multiply two arrays of
int
s:
int
int
x
[][] = {
{
3
,
2
,
3
},
{
5
,
9
,
8
},
};
int
int
y
[][] = {
{
4
,
7
},
{
9
,
3
},
{
8
,
1
},
};
int
int
z
[][] =
Matrix
.
multiply
(
x
,
y
);
Matrix
.
mprint
(
x
);
Matrix
.
mprint
(
y
);
Matrix
.
mprint
(
z
);

Consult a topic on numerical methods for more things to do with matrices; one of our re-
viewers recommends
Numerical Recipes in Fortran
by Teukolsky, Flannery, et al., available
as a
PDF
and for
online viewing
. The example recipes in that topic have been translated into
Java but are only available in this form to licensed purchasers of the
software
.
Commercial software packages can do some of these calculations for you; for one example,
see the numeric libraries available from
Rogue Wave Software
.
