SOURCE: Trying to get the inverse of a matrix

Hello,

The error may be due to the key you used to signifie inverse. It says in the manual that you should use the key x^-1 not the one used to input general powers.

Here is screen capture from the Appendix to the manual. The picture shows the sequence of keys to press to obtain the inverse of a 2x2 matrix. It is taken from page 41 of Appendix

The matrix used in the exemple is

a_11=2 a_12=1 a_21=1 a_22=2

SOURCE: How can I solve a matrix on my Casio fx-9750GA

Hi,

If you have mastered matrix manipulations on the TI calculators, it should be a breeze to learn the same on the Casios.**A. Define the matrix (Create it)**

- Turn calculator ON.
- Press Menu,select the MAT icon and press [EXE]
- You see a list of possible matrix labels (A, B, C,D,E,F)
- All that have not been created have a "none" to their right
- Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
- That is where you specify the dimensions (mxn). exemple. 2x2
- Enter the first dimension and press [EXE]
- Enter the 2nd dimension and press [EXE]
- A matrix template opens where you enter the coefficients left to right and up down.
- After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.

Press [SHIFT][QUIT] to return to the list of matrices to create new ones

Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..

- These operations are accessed as follows.
- Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
- Press [OPTN][F2:MAT]
- You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill

- You press the [OPTN][F2:MAT] key sequence (just above)
- Press [F3:Det]; the command
**det**is displayed on screen. - Press [F1:Mat] the identifier
**Mat**is displayed. - Press [ALPHA] A; screen display
**det Mat A**. - Press [EXE] to get the value of the determinant.

[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]

Product of two compatible matrices MatAXMatB

[OPTN][F2:MAT] (MAT) [Alpha] A [* ) (MAT) [ALPHA] B [EXE]

Hope it helps.

Thank you for using FixYa.

Press MODE 6 to get into matrix mode. Note: do this only once. If you do it again, it will erase all your matrices. Pick the matrix, set its dimension, then the calculator will put up a screen allowing you to enter/edit the matrix elements. At any time you're in matrix mode, press SHIFT 4 to bring up the matrix menu.

All this is explained in the manual beginning on page E-57. If you've misplaced the manual, you can download a copy from

Create a square matrix at mots 3X3. Then you can multiply it by a scalar, or scare it, or calculate its determinant, and inverse. With two matrices that have the same dimensions you can perform .additions/subtractions or multiplications.

You cannot program it. You can only use the features that were implemented on it at design time. These features are detailed in the instruction manual. Check the appendix: examples of all the possible calculations are given. The manual is available on the Casio website for downloading.

The Casio FX-570MS does not handle matrices. So you cannot create matrices, let alone invert them. Sorry.

The Casio FX115 ES handles matrices for up to 3X3 dimension. Create the matrix.Have its name displayed on the command line and press the [x^-1] (reciprocal ) key.

Sorry, this calculator can handle matrices with dimensions ranging from 1X1 up to 3X3 . To deal with 4X4 matices you need a graphing calculator such as the CASIO FX-9570G Plus, the Ti83Plus.

Let your system of linear equations be [A][X]=[B] where [A] is a 3x3 matrix, [X] is column vector ( a 3x1 matrix) , and [B] is also a column vector or (3x1) matrix.

Assuming you are able to invert the [A] matrix to find [A^-1].

Multiplying on the keft by [A^-1] the system of equations you get

[A^-1].[A][X]=[A^-1][B].

But since the product [A^-1][A] is the (3x3) Identity matrix, the left side of the equation is jut [X], while the right side is [A^-1][B]. As you can see it is not [B][A^-1] .

To solve your problem, you should define your [A] matrix, define the [B] column vector (3x1) matrix, then perform the operation [A^-1][B] using the [X to -1] power key to calculate the inverse [A^-1].

If you want to manipulate 6x6 matrices, you can use one of the CASIO Graphing calculators, such as theCFX-9850GPlus, or the FX-9750G plus.

Graphing calculators from other manufacturers can also handle such matrices. The FX-115ES can handle matrices with dimensions up to 3x3.

The parameter is the name of the matrix, available from the matrix menu SHIFT 4.

Hi,

The maximum number of dimensions is 3. Thus the largest matrix you can create is a 3x3 matrix. To verify that, press [MODE][6:Matrix][1:MatA] to get all available dimensions (3x3 to 1x1).

Hope it helps.

Hello,

The error may be due to the key you used to signifie inverse. It says in the manual that you should use the key x^-1 not the one used to input general powers.

Here is screen capture from the Appendix to the manual. The picture shows the sequence of keys to press to obtain the inverse of a 2x2 matrix. It is taken from page 41 of Appendix
