u Creating 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.
u To specify the dimensions (size) of a matrix
Example To create a 2-row × 3-column matrix in the area named Mat B
Highlight Mat B.

• 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.
u To input cell values
Example To input the following data into Matrix B:
1 2 3
4 5 6
1 2 3
4 5 6
