Question about Casio FX-115ES Scientific Calculator

- First you must set Matrix calculation: Press [MODE][6:Matrix].
- Then by entering one of the numbers [1:MatA] or [2:Matb] or [3:MatC] you get to choose the dimensions of the matrix (mxn].
- Once finished entering the matrix you clear the screen.
- The operations on A SINGLE matrix are available by pressing [Shift][Matrix].
- The choices are

- [1:Dim] to change the dimension of a matrix (in fact redefining the matrix)
- [2:Data] enter values in a matrix
- [3:MatA] access Matrix A
- [4:MatB] access Matrix B
- [5:MatC] access matrix C
- [6:MatAns] access the Answer Matrix (the last matrix calculated)
- [7:det] Calculate the determinant of a matrix already defined
- [8:Trn] The transpose of a matrix already defined

Once you have created a square matrix, for example matA.

You press [Shift][Matrix] [7:det] [SHIFT][MATRIX][3:MatA], close the parenthesis and press [ENTER].

If you have defined two similar matrices (same number of row and same number of columns) you can ADD them or subtract them. The operation keys are Plus and Minus as for any number.

To multiply you use the multiplication sign. The matrices must be compatible (mxn) multiplied by (nxk).

Use the Matrix Computational mode.

Select a Matrix label A, B or C Press EXE

Select the dimension (mXn)

A template opens to allow you to enter the coefficients.

You need to read about what kind of operations you can perform on matrices (addition, multiplication, raising to a power, etc.)

You need to have the computer scanned for trouble codes to proceed.

Most auto parts stores can scan for free in hopes of selling you some parts.

Once you have the codes you can research them online.

The TI-34 doesn't work with matrices.

Even if it did, you'd have to define what you mean by "compute." There are a lot of things that can be computed from a matrix, such as determinant, row and column norms, inverse, and eigenvalues.

How to Use the Pantech Matrix for the Internet1.Press the "Menu" key on your Pantech Matrix and click "Settings.

2.Click "Connections" and highlight "Modem Link." Press the "OK" key. Turn the modem link settings to "Inactive." Press the "End" key to exit to the phone's standby screen. 3.Download and install ActiveSync on your computer if the operating system is Windows XP. If you have a later version, download and install Windows Mobile Device Center. Follow the on-screen prompts to properly set up the program. 4. Press the "Menu" key on the Matrix and click "Settings." Scroll down to "Connection" and press the "OK" key. Click "USB" to "PC." 5. Open ActiveSync or Windows Mobile Device Center. Click "Device Settings." Click "Internet Sharing" under the "Programs" tab of the program. 6.Select "USB" from the drop-down menu under "PC Connection." Select "AT&T" from the "Network Connection" drop-down menu. 7.Click "Connect" and connect the Matrix to the computer using a USB cable. A status message of "Connected" will appear in the program's window when the connection is established.

The FX-991ES offers simple matrix operations like basic arithmetic, plus the slightly more complex operations determinant and inversion. Furthermore, it is limited to matrices with a maximum size of three rows and three columns.

The rank of a matrix is defined as the number of linearly independent row or column vectors. You can perform a simple partial test for square matrices by calculating the determinant of the matrix:

Unfortunately, this is all support the calculator offers. For small matrices (i.e. 4x4 or smaller), you should familiarize yourself with the Gau? Elimination Method algorithm for solving linear equation systems. It is a two-step procedure where a matrix first is converted to its row echelon form, and second to row canonical form to solve the LES.

You need to follow the algorithm only through the first part, the number of non-zero rows after this step equals the rank of the matrix. With a little exercise you will be able to do it faster on paper than trying to do it with your calculator only.

For larger matrices I suggest to use a PC with more powerful math software (Maple, Mathematica, ...) or, if you know some basic computer programming, just write the necessary program yourself, which is also a very good exercise both in programming and understanding the algorithm.

Dot Matrix printers were never made 'Plug and Play"

You have to hard install them with the driver disk, most setups for dot Matrix can be downloaded from epson and the L300 is definitely there in support download drivers

please rate my help++++Thanks for using FIXYA

According to the user manual (available here: http://www.refurbups.com/KB-M-Matrix) this can only be reset by using the PowerChute software available from www.apc.com and requires the unit to be connected to a computer.

A plug in computer reader is needed to reset the computer. Did a shop do the work? - they should know better. Take it back and have'em reset it. If you did it, then you could buy the reader (expensive) or go the way of the shop option
