=
and
ƒ
(
TEST
menu), they must have the same dimensions.
=
and
ƒ
compare
matrixA
and
matrixB
on an element-by-
element basis. The other relational operations are not valid
with matrices.
matrixA
=
matrixB
returns
1
if every comparison is true; it
returns
0
if any comparison is false.
matrixA
ƒ
matrixB
returns
1
if at least one comparison is
false; it returns
0
if no comparison is false.
iPart(
(integer part),
fPart(
(fractional part), and
int(
(greatest integer) are on the
MATH NUM
menu.
iPart(
returns a matrix containing the integer part of each
element of
matrix
.
fPart(
returns a matrix containing the fractional part of
each element of
matrix
.
int(
returns a matrix containing the greatest integer of each
element of
matrix
.
