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.
To specify the dimensions (size) of a matrix
Example To create a 2-row
Highlight Mat B.
Specify the number of rows.
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.
To input cell values
Example To input the following data into Matrix B:
1 1
