An informational screen appears. Note If you ever need technical support, you may need the version number shown on this screen. 3. [. . . ] For example: [ [1, 2] [3, 4] ] Ü [A] and [ [1, 2] [3, 4] ] ¦ 3 are valid because they contain two matrix operations (the input matrix is created in the calculator’s memory, and so is the resulting output matrix). Matrices for the MIX 33 Page 17 If an expression has three or more such operations, an error occurs. In most cases, however, you can perform the operations successfully by breaking them into separate pieces. For example: An error occurs for: Instead, enter: [ [1, 2] [3, 4] ] + [ [5, 6] [7, 8] ] [ [1, 2] [3, 4] ] Ü [A] [ [5, 6] [7, 8] ] Ü [B] [A] +[B] [ [1, 2] [3, 4] ] Ü [A] [ [5, 6] [7, 8] ] Ü [B] augment( [A] , [B] ) identity(3) Ü [A] randM(3, 3) Ü [B] [A] * [B] augment([ [1, 2] [3, 4] ] , [ [5, 6] [7, 8] ]) identity(3) * randM(3, 3) Note These expressions cause an error because they contain three matrix operations (two input matrices and one result matrix). Matrices for the MIX 33 Page 18 Typing a Matrix Directly from the Keyboard On the Matrix Home screen, use the syntax: [ [element1, 1, . . . , element1, n], . . . , [elementm, 1, . . . , elementm, n] ] Use [ (press &) to begin the matrix. Note: At the start, [ [ begins the matrix and then begins the first row. Note: The closing ] ] are not necessary at the end of an expression or preceding Ü (X). Any expressions are evaluated when you press b. For example: The commas that you must enter to separate elements are not displayed on output. To store a matrix directly to a matrix variable, use X. For example: Select the matrix from the Matrix NAME menu or type it directly. Press & and ' to type [ and ]. Matrices for the MIX 33 Page 19 Accessing a Specified Matrix Element On the Matrix Home screen, you can store a value to, or recall a value from, a specified matrix element. Use the syntax: [matrix] (row, column) Matrices for the MIX 33 Page 20 Displaying and Copying Matrices on the Matrix Home Screen Displaying a Matrix To display the contents of a matrix on the Matrix Home screen, select the matrix from the MATRIX NAME menu and then press b. If the matrix is too large to be displayed on the screen, press ", !, #, and $ to scroll the matrix. # or $ in the right column indicates additional rows. Ellipses (. . . ) in the left or right column indicate additional columns. Matrices for the MIX 33 Page 21 Copying One Matrix to Another To copy a matrix: 1. You can either use # and $ to highlight the number to the left of the matrix name and then press b, or simply press the corresponding number key. For example: For Ü, press X. [ [1, 2, 3] [3, 2, 1] ] Ü [B] You can also press & and ' to type [ and ] directly from the keyboard. Matrices for the MIX 33 Page 41 Deleting a Matrix From the Matrix Home Screen Use the DelVar instruction available from the CATALOG. From the MEMORY Menu 1. (Because matrices are not standard variables on a TI. 73, they are stored as application variables. ) 5. Use # and $ to move the 4 pointer to the applicable matrix name. Note On this calculator screen, matrix names are shown as MATA and MATB instead of [A] and [B]. 6. Continue deleting matrices as necessary. Matrices for the MIX 33 Page 42 Uninstalling the Application from Your MIX 33 To uninstall the application and delete it from the calculator’s memory: 1. If you retained the application file on your computer, you can reinstall it later. Matrices for the MIX 33 Page 43 Error Recovery Instructions Low Battery Condition Do not attempt a Flash download if the low-battery message appears on the calculator. If you receive this error during an installation, change the batteries before trying again. Check Amount of Flash Application Free Space On the MIX 33, select - Ÿ 3:Check APPs…. The number to the right of Spaces Free: indicates the number of spaces available for applications. Communication Error This error indicates the Flash installer is unable to communicate with the MIX 33. The problem is usually associated with the TI-GRAPH LINK™ cable and its connection to the MIX 33 and/or to the computer. Make sure the cable is firmly pushed in to the calculator and the computer. Matrices for the MIX 33 Page 44 If this does not correct the problem, try a different TI-GRAPH LINK cable and reboot your computer.
