To use the Visual Basic program that performs the arithmetic for your chosen row operations, do the following:
www.engr.mun.ca/~ggeorge/1405
".linsys.exe
".
For Microsoft Internet Explorer Version 4 or 5:
{ For other browsers:
}
linsys.exe
" in a
directory of your choice. linsys.exe
"
(in the directory that you chose in step iv)
The main program window should now appear. Change the value of any entry that is not correct. Each entry is presented in the form numerator / denominator. In most cases, you will have to change most of the numerators but few or none of the denominators.
An entry can be overwritten by double-clicking the mouse on that entry, and typing the new value in the box. The old entry can be edited by single-clicking the mouse on that entry and using delete or backspace keys to erase unwanted digits.
Once you have begun applying row operations in step (xi) below, do not change the table entries manually again.
Once the linear system is correct, then select your first row
operation. Click on the row to change (bottom left box),
the row to use (near bottom centre) and in the pair of boxes near
the bottom right corner enter the multiple of the latter row to be
subtracted from the former row.
[Some row operations do not need some of this information].
When ready, click on the appropriate row operation button.
Your output is now stored in the filename that you chose in step (vii). Use your favourite word processing program (Notepad, DOS Editor, Word, etc.) to view the output file. You can also print the output file - it is a plain text file that any printer should be able to understand.
