Program "Simplex2" to perform the simplex
method on an initial simplex tableau on a TI 83 or TI 84 (The
program asks where your matrix is. Press MATRX and the down arrow
if necessary to select your matrix. Then, press ENTER. The
program alters the matrix [B] as it performs the simplex method).

Note: In the text listings, \->\ represents the
STO-> key in the left column.
Note: To use the binary version of the program, you will
first need to download it. To download it, right click the appropriate
link and choose
"Save target as..." with Internet Explorer or "Save link
as..." with Netscape. The downloaded file should have the indicated
length. If you have problems following these instructions,
please send e-mail to arosenthal@salemstate.edu).
After being downloaded, the binary version of the
program may be loaded directly into the TI calculator of the corresponding
type, IF you have a "TI-GRAPH LINK" cable to connect your PC and the calculator
and you use the appropriate "TI-GRAPH LINK" software available for free
download at http://education.ti.com/product/accessory/link/down/download.html.
There are "TI-GRAPH LINK" cables connected to several of the computers
in the Math Lab which you may use in the Math Lab. The "TI-GRAPH
LINK" software is already installed on some of the computers in the Math
Lab. If you have trouble finding it, please ask for help.
If you have a "TI USB connectivity kit" cable and TI-Connect version 1.6 (or later) software installed on your computer, it is even easier to load the binary version of "Rowop" onto your TI calculator. (TI USB cables and TI-Connect software are already present on many of the computers in the Math Lab. If you have trouble finding such a computer, please ask for help. TI-Connect is available for free download at http://education.ti.com/educationportal/appsdelivery/download/download_select_product.jsp?cid=us if you click on the link for Free Computer Software and then click on the link for TI-Connect Software for Windows or Macintosh, whichever is appropriate for your computer). After TI-Connect version 1.6 or later is installed on your computer, plug the USB part of the USB cable into a USB port on your computer and the pointy part of the USB cable into your TI calculator. Then, turn on your calculator. Use the mouse on your computer to right-click on the binary program file you downloaded to your computer. Select "Send to TI device". Select the file and choose Destination RAM. Then, click on "Send to Device" at the bottom of the screen. The binary file will then be transferred to your TI calculator.
