Function
n
G
n -
X->X:
Performs the
subtraction
of
matrix X
elements
from
scalar n.
In
this
operation,
each element
of
matrix
Xis subtracted from n
and
the result becomes the correspondi
n g
elements
of new
matrix
X.
NOTE:
Mathematically,
such
an
operation
as this does
not
exist. The subtraction of scalars is another
feature
uni-
que
to
the
COMPUTER.

Stores
the
value of matrix
X
in the
memory location of
matrix M
(while clearing
the previous
contents
of
matrix
