The dimensions of the display grid can be set using the Number Mode tab of the Options dialog. When the dimensions are greater than 1x1, additional functions become available as described below when the shift button is depressed. Some functions are dependent on certain restrictions on dimensions for them to be available.
It may be necessary to enlarge the display by changing the size of the calculator window in order to see the grid of values.
Many arithmetic functions can be performed on arrays or matrices. In addition, the grid can be selectively given values by using the cursor. When a single cell is selected the other cells are greyed. Multiple cells can be selected by clicking and then moving the cursor with the left mouse button depressed. Only selected cells are modified by keyboard input.
The ).( button computes the scalar (dot) product of two vectors.
The )x( button computes the vector (cross) product of two vectors.
The ind button results in each element of the grid being given the value of its index.
The T button computes the transpose of a matrix.
The )( button computes the product of two matrices.
