Hello,

I assume yoy know how to define your matrix, but I will repeat it here for others who might not know. You can skip to **Calculation**

1.Turn Calculator ON. If there are no icons, press [MENU].

Data Entry

2.Use arrows to highlight [MAT] icon. Press [ENTER]

3.Highlight the first line where it says Mat A. Use the right arrow to enter the dimensions of Matrix A. Enter 3 and press [EXE]. The cursor moves to the second dimension. Press 3 and press [ENTER].

4. The matrix entry screen appears.

5. Enter first matrix coefficient a_11 and press [ENTER]

6. Enter a_12 and [ENTER]

.....

Key in last coefficient a_33 and press [ENTER]**Calculation**

Press [MENU] and [RUN]

Press [OPTN][F2:MAT][F3:Det] Command echoes on screen as **det**

Press [F1:Mat] echoes on screen as Mat; screen shows **det Mat**

Press [ALPHA] A The screen displays **det Mat A**

Press [ENTER] to calculate the determinant.**If the matrix is not square, you cannot calculate its determinant.**

Hope it helps..

It is difficult to know exactly WHY it gives you inaccurate values, or does it? I am inclined to believe that you might (just might) have made mistakes entering the data. (A single error in an extreme value will affect the mean).

I would blame the calculator only after I have made certain that I did not make mistakes myself. (That is my way of doing things.)

You have the relation [A]^-1 **(inverse of A) =Adj([A])/det([A])**

Create a square matrix [A]

Calculate its determinant det(A) and store it in some variable (why not D). Calculate the inverse of A. Multiply the result by the determinant.

Once the matrix is created you can use the reciprocal key to get the inverse.

I hope you will not hold against me if I showed the whole porocess. (No reflexion on your or anybody's abilities to create a matrix. Just trying to be helpful to more people.)

Press Menu to display icons.

Press 1 or use Arrows to highlight Run/Mat.Press EXE

Press the F1 key to activate the Mat TAB.

While a matrix label is higlighted press F3:Dim to enter the dimensions.

Matrix must be square.

Fill her up!

Press EXE after entering the last element.

Then press EXIT to return to the Run/Mat Screen.

In Run/Mat screen press the OPTN key. Press F1 to enter the Mat identifier

followed by [ALPHA] A (if the matrix you created is stored in A)

At this point the screen displays Mat A.

Any of the continuations of the command shown below will yield the inverse matrix.

The minus sign you see in the 2nd and 3rd commands below is the change sign (-)

For the bogus 2X2 matrix I entered, the result is as follows.

Notice that even if inside the answer matrix the elements are displayed as decimals, the

values you will see at the bottom are exact fractions.

Given a square matrix, you can find its determinant by using the determinant function available through SHIFT 4 7. SHIFT 4 brings up the matrix menu, and 7 selects the determinant function.

Refer to the "Matrix Calculations" section in the manual, beginning on page E-57, and items #096-105 in the appendix. If you've misplaced your manual and/or appendix, you can download them from

I am afraid that "find the solution of a matrix" does not mean anything. However if you want to perform some arithmetic operations on the matrices ( multiplication, addition, subtraction) you can do so using the regular operation keys.

If on the other hand you want to calculate determinants of square matrices, inverse square matrices etc.

Go to the RUN/MAT screen and press [OPTN, then press F2 to open access these operations and this is what you see.

F1 type the MAT identifier in command line

M>L converts a matrix to a list

Det calculates the Determinant of a square matrix

Trn transposes the matrix,

etc.

To invert a square matix, use the [X^-1] key e.g. MatA^-1
