To compare two matrices using the relational operations =
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
.
