What's the determinant of the numbers in matrix A? A singular matrix is a matrix whose determinant is zero.

One example: the determinant of a 4x4 identity matrix is 1.

Use the matrix editor to create a 4x4 matrix with 1s along the main diagonal (upper-left to lower-right) and 0s elsewhere. Then use the det() function to calculate the determinant of this matrix.

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 =.

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

Hello,

You cannot calculate the inverse of an arbitrary matrix. It must be a square matrix (nxn) with non zero determinant. Make sure dimensions m and n are equal. (2x2), (3x3)

To calculate its determinant [Shift][MATRIX] [7:det] [SHIFT][MATRIX][3:MatA] close the right parenthesis and [=].

If determinant is different from zero then you can calculate its inverse.

If matrix MatA has already been defined, you calculate its inverse as follows;

[SHIFT][MATRIX][3:MatA] [X^-1][=]. Use the X to -1 power , the one under [MODE].

For well-behaved matrices you calculate the inverse directly without worrying about the determinant.

Hope it helps.
