Deleting Matrices - Casio FX-9750G Quick Start Manual

• All of the cells of a new matrix contain the value 0.
• If "Mem ERROR" remains next to the matrix area name after you input the dimen-
sions, it means there is not enough free memory to create the matrix you want.

Example To input the following data into Matrix B :

(Data is input into the highlighted cell.
Each time you press w, the highlight-
ing move to the next cell to the right.)
• Displayed cell values show positive integers up to six digits, and negative inte-
gers up to five digits (one digit used for negative sign). Exponential values are
shown with up to two digits for the exponent. Fractional values are not displayed.
• You can see the entire value assigned to a cell by using the cursor keys to move
the highlighting to the cell whose value you want to view.
• The amount of memory required for a matrix is ten bytes per cell. This means that
a 3 ! 3 matrix requires 90 bytes of memory (3 ! 3 ! 10 = 90).
