• {DIM} ... specifies the matrix dimensions (number of cells)
• {CSV} ... stores a matrix as a CSV file and imports the contents of CSV file into one of the
matrix memories (Mat A through Mat Z, and MatAns) (page 2-48)
• {M⇔V} ... displays the Vector Editor screen (page 2-60)
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

u To input cell values
Example To input the following data into Matrix B:
The following operation is a continuation of the example calculation on the previous page.
