Number of rows and columns
# The two matrices must have the same
dimensions in order to be added or
subtracted. An error occurs if you try to
add or subtract matrices of different
dimensions.
# For multiplication (Matrix 1
!
Matrix 2), the
number of columns in Matrix 1 must match
the number of rows in Matrix 2. Otherwise,
an error occurs.

Matrix Calculations
# When performing matrix arithmetic operations,
inputting the Identity command at the location
of a matrix command (such as Mat A) makes it
possible to perform identity matrix
calculations.
