Press the MODE key. and press 4 for MATRIX.
To enter a matrix press the MATH button and choose 2 for EDIT. Determine the size of your matrix by typing in the row x column value (maximum 4). Then press =. Type in the values in your matrix. After each value press = to move to the next part of the table. Once your matrix is complete press ON and then the MATH button. This time choose 4 for STORE. Select the matrix name you would like to store your matrix in - for example choose 0 for matA. Now press MATH and press the down arrow key once. Select 6 for CALC and choose 0 for det (determinant). Then input the matrix you want the determinant of by pressing MATH and 1 for MATRIX. Select the matrix you would like to work with eg, matA and press then press =.
Here is an account of what you can do with matrices on this scientific calculator. Certain precautions must be taken as concerns the dimensions of the matrices. Refer to your text book on matrix algebra. On this calculator the largest matrices you can define have dimensions 3X3.
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
[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].
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).
a friend sent me a pantech phone AT&T where you able to find a solution? I found some info from Sulit.com for phones being used to open At&t so far I have not heard from the person. thanks
it could be the following Taking a Quick Look The E1 F2 error message indicates the control board thinks the touch panel has been unplugged from the board or it cannot read the switches. How it Works The panels on these ovens utilizes a switching matrix to constantly monitor all the buttons for a key press. By using a matrix for switch input, many buttons can be read by the processor using very few wires. The unfortunate side of a switch matrix is if any one wire becomes damaged, an entire row of switches on the matrix will no longer be usable since they cannot be seen by the control board.
getting a qualified engineer to check this touch panel and suspect touch panel maybe defective and need replacing.
Use the matrix mode in the calculator. In that mode you will be asked what the order of the matrix. Select the matrix of the desired order. After that you will be asked to enter the elements of the matrix. Then you will be redirected to your normal screen. Select the shift button and press the button with matrix written on the top of the button. Push that and you will find an option to find the determinant of the given matrix. Good Luck
This could be an connection problem of your matrix screen.
When you open the phone you will see a flatcable with a litte flat cable connected on that cable it could be that the little one isn't fitted well the flat cable is from your LCD screen and the Little flat cable that is fitted on that Flat cable is from the matrix screen (Touch screen).
If your car has climate control, remove the glovebox, and change the heater temp from the lowest to the highest setting. you should hear the electric motors pulling cables in the dash. it's probably a faulty control unit in the dash, you're certain there's hot water going through the matrix?
