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.
matrixAƒmatrixB 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.
