Matrices


Matrices can be typed in by row or edited in the matrix editor. The editor is accessed by pressing



First, select a name in the menu to the right. Then, enter the dimension of the matrix.



Press Navigate among the rows and columns using the cursor keys. Press the key to move to the next element on the right and from the end of one row to the beginning of the next.



There are several matrix operations in the matrix menu listed under, OPE and MATH.



Many normal operations such as addition, multiplication, x-1, and even sine work on matrices, though they are often given different definitions in this context.


Note: When viewing a matrix to large to fit on the screen use the cursor keys to see more.
