A spreadsheet to implement Newton's method to solve the system of 3 equations in 3 unknowns in problem 2b from p. 680

Some notes on how to perform elementary row operations on a graphing calculator and with an Excel spreadsheet  (in pdf format)
Note:  To view or print out pdf files, you may need the Adobe Acrobat reader, which you may download for free if you don't have it yet by clicking  here.

A spreadsheet that can be used with Excel to pivot matrices  (in xls format)  (I recommend right-clicking on this link and saving it to your computer's hard drive.  Then, navigate to the directory where you saved it and double click on ExcelPivot.xls).    If this spreadsheet won't work on your computer, click here for instructions that might help you fix the problem.

A Linear Algebra toolkit that can perform row operations on a matrix and obtain its reduced row echelon form

A simplex method tool   (Note:  This tool requires all constraints to be written with the right-hand side nonnegative.  The objective function can't have any constant terms in it.  If a variable appears in a constraint but not in the objective function, be sure to include it in the objective function with a coefficient of 0).

A spreadsheet that illustrates using Solver (Tools/ Solver with Excel) and the simplex method to solve a linear programming problem

A script (rowop.m) which you may use with MATLAB (in the Math Lab) to pivot matrices.  (This may be useful when performing Gaussian elimination or when using the simplex method).  I recommend right-clicking on the above link and saving it to your computer's hard drive.  Then, open MATLAB and click on "File" "Run Script" and navigate to the directory where you saved rowop.m.  Click on rowop.m and then click on "Open" and "OK".  To input your matrix, enclose it in brackets and separate each row with a semicolon.  For example, to input a 3 by 3 identity matrix, type
[1 0 0;0 1 0;0 0 1]

A script (rowop.sci) which you may use with SCILAB to pivot matrices  (This may be useful when performing Gaussian elimination or when using the simplex method).  I recommend right-clicking on the above link and saving it to your computer's hard drive.  To use this, you may need to download and install SCILAB from http://www.scilab.org  .    Then,  open SCILAB and click on "File" "Exec"  and navigate to the directory where you saved rowop.sci.  Click on rowop.sci and then select "Open".   To input your matrix, enclose it in brackets and separate each row with a semicolon.  For example, to input a 3 by 3 identity matrix, type
[1 0 0;0 1 0;0 0 1]
(You could also type eye(3,3) to input a 3 by 3 identity matrix).

Program "Rowop" with prompts to perform elementary row operations on a matrix [A] on TI calculators:
TI 82 binary version (397 bytes);  TI 82 text listing of program
TI 83 binary version (396 bytes);  TI 83 text listing of program;  (Use the TI 83 version if you have a TI 84)
TI 85 binary version (522 bytes);  TI 85 text listing of program   (Use the TI 85 version if you have a TI 86)

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.  With some versions of Netscape, it may be corrupted and have a different length. In that case, please use Internet Explorer or click here to find another link that might enable you to download this file properly. If you have problems following these instructions, please send e-mail to arosenth@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/us/product/apps/latest.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/en/us/software/search  if you click on the link for TI-Connect  Software for Windows ).   After TI-Connect version 1.6.1 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.

A spreadsheet to implement Newton's method to solve the KKT equations using Newton's method for Example 20.2-5 on p. 696 
I chose the initial guess to be feasible (with x >=1, y >=2 and z >=0).
