SOURCE: how to calculate inverse of a 3x3 matrix in casio

Hello,

Here is the solution for th FX-991ES.

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

Here is the link to download the manual and the appendix

http://support.casio.com/manualfile.php?rgn=1&cid=004001004

The link is for FX991ES. Look there foe you manual.

Hope it helps

SOURCE: How to do matrix multiplication on Casio 115ES?

Hello

First you must set Matrix calculation

[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 matrices are available by pressing [Shift][Matrix]

[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

To add matrices MatA+MatB

To subtract MatA-MatB

To multiply MatAxMatB

To raise a matrixe to a power 2 [x2], cube [x3]

To obtain inverse of MatA already defined MatA[x-1] [x-1] is the x to the power -1 key

Dimensions of matrices involved in operations must match (see you textbook for the rules)

Read the appendix to your user manual, there are several exemples.

SOURCE: when i press the MODE button in my CASIO fx - 911ES

Hello,

Just in case : Press [SHIFT][CLR] (9) [3: ALL] to reset the calculator and try [MODE] again.

If that does not work, your calculator may be defective or a fake (not the genuine article). If at all possible, return it to where you bought it and get a refund.

Here is a picture of the FX-115ES, its face looks like the 991ES. Hope I am mistaken.

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.

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.)

The following was written for the Casio FX-991 ES. If matrix calculations are available on your calculator you will perform them as described below. ( I have no time to verify that the FX-991ms can perform matrix calculations).

Let me explain how to create matrices. (If you know how to do it, skip to the operations on matricies, at the end.)

First you must set Matrix calculation

[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

[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

To add matrices MatA+MatB

To subtract MatA-MatB

To multiply MatAxMatB

To raise a matrixe to a power 2 [x2], cube [x3]

To obtain inverse of MatA already defined MatA[x-1] [x-1] is the x to the power -1 key

Dimensions of matrices involved in operations must match.

Here is a short summary

The multiplication of structured mathematical entities (vectors, complex numbers, matrices, etc.) is different from the multiplication of unstructured (scalar) mathematical entities (regular umbers). As you well know matrix multiplication is not commutative> This has to do with the dimensions.

An**mXn **matrix has** m rows **and**
n columns**. To perform multiplication of an **kXl** matrice by
an **mXn** matrix you multiply each element in one row of the first
matrix by a specific element in a column of the second matrix. This
imposes a condition, namely that the number of columns of the first
matrix be equal to the number of rows of the second.

Thus, to be able to multiply a kXl matrix by am mXn matrix, the number of columns of the first (l) must be equal to the number of rows of the second (m).

So**
MatA(kXl) * MatB(mXn) is possible only if l=m**

MatA(kX3) * Mat(3Xn) is possible and meaningful, but

Mat(kX3) * Mat(nX3) may not be possible.

To get back to your calculation, make sure that the number of columns of the first matrix is equal to the number of rows of the second.** If this condition is not satisfied, the calculator
returns a dimension error**. The order of the matrices in the
multiplication is, shall we say, vital.

I know this is a long time ago, but i am sure someone might ask eventually this same question.For the Casio fx-115es here are the instructions:go to mode, matrix, and pick the matrix you want to you.. you only have 3 options.create your matrix and press AC.Here is the tricky part, DO NOT go to mode again, that will reset your matrices that you have entered. Instead, press shift and the number 4 key, which is also matrix, go to press 1 (DIM), chose the other matrix to enter, and you can start mult, adding, etc.Any time you want to use the entered matrices, go through the matrix function, not the mode function.
