This
is the Microworld version of the Mathwright WorkBook:
Row Reduction. It has
a tool that one may use to row reduce matrices. In the Microworld, you may
create a new zero-initialized or randomly initialized matrix of any dimension.
You may also enter your own matrix, or modify the most recent displayed matrix
by editing it onscreen. Finally, you may augment the current matrix with the
appropriate identity matrix, so that you can generate the inverse matrix onscreen
as you row reduce.
The
row operations are:
- Exchange two rows
- Multiply a row by
a nonzero constant
- Add a constant times a row to another row
There
are two pages. On the first page, all operations are exact rational operations,
unless the reader enters decimals in the matrices. And on the second page,
all operations are decimal to the decimal precision that you choose.
There
is a "Help" page that explains how to enter your own matrices. On the main
page, the reader has an array of standard tools to implement the row operation
on the current matrix, or to start from scratch with a new matrix.
