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.
Hope helps

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)

  1. Turn calculator ON.
  2. Press Menu,select the MAT icon and press [EXE]
  3. You see a list of possible matrix labels (A, B, C,D,E,F)
  4. All that have not been created have a "none" to their right
  5. Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
  6. That is where you specify the dimensions (mxn). exemple. 2x2
  7. Enter the first dimension and press [EXE]
  8. Enter the 2nd dimension and press [EXE]
  9. A matrix template opens where you enter the coefficients left to right and up down.
  10. After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.
At the bottom of the screen you have 3 menus for Row and column manipulations. But those will have to wait for now.
Press [SHIFT][QUIT] to return to the list of matrices to create new ones

Operations on matrices
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..
  1. These operations are accessed as follows.
  2. Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
  3. Press [OPTN][F2:MAT]
  4. You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill
Exemple : calculate the determinant of a matrix A (already defined).
  1. You press the [OPTN][F2:MAT] key sequence (just above)
  2. Press [F3:Det]; the command det is displayed on screen.
  3. Press [F1:Mat] the identifier Mat is displayed.
  4. Press [ALPHA] A; screen display det Mat A.
  5. Press [EXE] to get the value of the determinant.
Square of Matrix A
[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.

This post is rather exhaustive as regards the matrix capabilities of the calculator. So if the post recalls things you already know, please skip them. Matrix multiplication is at the end.

Let me explain how to create matrices. (If you know how to do it, skip to the operations on matrices, 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
(mxn]. Once finished entering the matrix you clear the screen.

[2:Data] enter values in a matrix

[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 (MUST have identical dimensions same m and same n, m and n do not have to be the same)
To subtract MatA-MatB. (MUST have identical dimensions, see above)
To multiply MatAxMatB (See below for conditions on dimensions)
To raise a matrix to a power 2 [x2], cube [x3]
To obtain inverse of a SQUARE MatA already defined MatA[x-1]. The key [x-1] is the x to the power -1 key. If the determinant of a matrix is zero, the matrix is singular and its inverse does not exit.

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 numbers). 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 matrix 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.

How do i put my casio fx -100ms in matrix mode and how do i solve


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.)

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.
