IInputting and Editing Matrices

Pressing (MAT) displays the Matrix Editor screen. Use the Matrix Editor to input and edit matrices.

m σ n … m (row) σ n (column) matrix

•{DEL}/{DEL•A} ... deletes {a specific matrix}/{all matrices}

•{DIM} ... {specifies the matrix dimensions (number of cells)}

SCreating a Matrix

To create a matrix, you must first define its dimensions (size) in the Matrix Editor. Then you can input values into the matrix.

STo specify the dimensions (size) of a matrix

A

(DIM) (This step can be omitted.)

Specify the number of rows.

AU

Specify the number of columns.

•All of the cells of a new matrix contain the value 0.

•Changing the dimensions of a matrix deletes its current contents.

•If “Memory ERROR” remains next to the matrix area name after you input the dimensions, it means there is not enough free memory to create the matrix you want.

STo input cell values

Example To input the following data into Matrix B:

1 2 3

4 5 6
